A bakery offers a sale price of $3.00 for 6 muffins. What is the price per dozen?

Answer:

x = 36

y = -1

Step-by-step explanation:

The substitution method is when the value of one variable from one equation is substituted in the other equation.

y = 10/3x - 121

y = 5/4x - 46

In this case you substitute one of the equations for y.

5/4x - 46 = 10/3x - 121

Lets set the coefficient being multiplied by x to a number with a common demoninator.

15/12x - 46 = 40/12x - 121

Next isolate x and combine like terms.

15/12x - 46 = 40/12x - 121

-15/12x          -15/12x

-46 = 25/12x - 121

+121              +121

75 = 25/12x

*12/25    12/25

36 = x

------

Now lets plug x in to solve for y

(you pick either equation to do this)

y = 5/4(36) - 46

y= 45 - 46

y = -1

Answer:

x > 2

Step-by-step explanation:

To solve for x, we will first simplify the left side of the inequality by finding a common denominator for the fractions:

5/6x - 1/3 > 4/3

Multiplying both sides by 6 to eliminate the fractions, we get:

5x - 2 > 8

Adding 2 to both sides, we have:

5x > 10

Dividing both sides by 5, the final answer is:

x > 2

The phrase "it is a subset of any X ∈ C" indicates that the subject in question (denoted by "it") is a subset of every element X that belongs to the set C. In other words, whatever "it" refers to is contained within every element of the set C.

The phrase "it is a subset of any X ∈ C" indicates that the subject in question (denoted by "it") is a subset of every element X that belongs to the set C. In other words, whatever "it" refers to is contained within every element of the set C.

To provide a clearer understanding, let's break it down further:

"Subset": A subset is a collection of elements that are all contained within another set. If set A is a subset of set B, it means that every element of A is also an element of B.

"Any X ∈ C": Here, X represents a generic element of the set C. The phrase "X ∈ C" denotes that X belongs to the set C. It implies that X is one of the elements within the set C.

Combining the two parts, "it is a subset of any X ∈ C" means that "it" (referring to a specific set or collection of elements) is included in every element X of the set C. In other words, every element of C contains "it" as a subset.

The absolute value equation for x = -4 can be written as:

|x - (-2)| = 2

We have,

For x = -8, the absolute value equation can be written as:

|x - c| = d

Substituting x = -8 into the equation, we have:

|-8 - c| = d

To satisfy the given solution set, we need to determine the values of c and d that make the equation true.

Since x = -8, the absolute value of -8 minus c should be equal to d.

For x = -8, a suitable choice of c would be -12 and d would be 4.

This gives us:

|-8 - (-12)| = 4

|4| = 4

Therefore, the absolute value equation for x = -8 can be written as:

|x - (-12)| = 4

Similarly, for x = -4, the absolute value equation can be written as:

|x - c| = d

Substituting x = -4 into the equation, we have:

|-4 - c| = d

To satisfy the given solution set, we need to determine the values of c and d that make the equation true.

Since x = -4, the absolute value of -4 minus c should be equal to d.

For x = -4, a suitable choice of c would be -2 and d would be 2. This gives us:

|-4 - (-2)| = 2

|-2| = 2

Answer:

628.3 cubic inches

Step-by-step explanation:

Since the base diameter of the cylinder is d=20 inches, so its radius r is:

[tex]r=\frac{d}{2}=\frac{20}{2}=10[/tex]

Then, the volume V of the cylinder with radius r=10 inches and height h=2 inches is:

[tex]V=\pi r^{2} h=\pi\times 10^{2}\times 2=628.3[/tex]

Answer:

To find the volume of a cylinder, we need to use the formula V = πr^2h, where V is the volume, r is the radius of the base, and h is the height. Since we are given the diameter of the base, which is 20 inches, we can find the radius by dividing it by 2. So, r = 20 / 2 = 10 inches. The height is given as 2 inches. Plugging these values into the formula, we get:

V = π(10)^2(2)

V = π(100)(2)

V = 200π

To get the volume in cubic inches, we need to multiply this by the conversion factor of 1 cubic inch per cubic inch. This does not change the value, but it gives us the correct units. So,

V = 200π cubic inches

To round this to the nearest tenths place, we need to look at the hundredths digit. If it is 5 or more, we round up; if it is less than 5, we round down. Using a calculator, we can approximate π as 3.14. So,

V ≈ 200(3.14) cubic inches

V ≈ 628 cubic inches

The hundredths digit is 0, which is less than 5. So we round down and keep the tenths digit as it is. Therefore,

V ≈ 628.0 cubic inches

Let's calculate the total cost of the bike and the dining table first.

The cost of the bike is ₹56,725.

The cost of the dining table is ₹8,800.

To find the total cost, we add the cost of the bike and the cost of the dining table:

₹56,725 + ₹8,800 = ₹65,525

So, the total cost of the bike and the dining table is ₹65,525.

To determine which item is costlier, we compare the costs of the bike and the dining table. In this case, the bike is costlier as it costs ₹56,725, while the dining table costs ₹8,800.

Now, let's calculate the amount that Somraj deposited in his wife's account.

He initially had ₹1,78,500 in his bank account and withdrew the entire amount along with the interest of ₹20,489. Therefore, the total amount withdrawn is:

₹1,78,500 + ₹20,489 = ₹1,98,989

From this amount, he spent ₹36,725 on the laptop, ₹8,800 on the dining table, and ₹56,725 on the bike. So, the total amount spent on these items is:

₹36,725 + ₹8,800 + ₹56,725 = ₹1,02,250

To find the amount deposited in his wife's account, we subtract the total amount spent from the total amount withdrawn:

₹1,98,989 - ₹1,02,250 = ₹96,739

Therefore, Somraj deposited ₹96,739 in his wife's account.

Answer:

a. 65,525

b. bike

c. 96,739

Step-by-step explanation:

a.

total cost of the bike and the dining table,

= 56,725 + 8,800

= 65,525

b.

bike is costlier than the dining table.

c.

total amount somraj received from bank

= 1,78,500 + 20,489

= 198,989

total expenditures

= 36,725 + 8,800 + 56,725

= 102,250

amount he saved to deposit in his wife's account

= 198,989 - 102,250

= 96,739

Applying the Angle Addition Postulate, the measure of angle BDC is calculated as: 57 degrees.

The Angle Addition Postulate establishes that when two angles are adjacent, the measure of the resulting angle formed by their combination is equal to the sum of their individual measures.

Therefore, according to the Angle Addition Postulate, we would have:

(-6x + 11) + (-7x + 15) = 104

Solve for x:

-6x + 11 - 7x + 15 = 104

-13x + 26 = 104

-13x = 104 - 26

-13x = 78

x = -6

The solution to the system of equations using Cramer's rule is x = -1 and y = 2.

To solve the system of equations using Cramer's rule, we'll need to determine the values of x and y by calculating the determinants of various matrices.

The given system of equations is:

8x + 5y = 2 (Equation 1)

2x - 4y = -10 (Equation 2)

First, let's calculate the determinant of the coefficient matrix, D:

D = |8 5|

|2 -4|

D = (8 * -4) - (5 * 2)

D = -32 - 10

D = -42

Next, we'll calculate the determinant of the matrix formed by replacing the x coefficients with the constants from the right side of the equations, Dx:

Dx = |2 5|

|-10 -4|

Dx = (2 * -4) - (5 * -10)

Dx = -8 + 50

Dx = 42

Similarly, we'll calculate the determinant of the matrix formed by replacing the y coefficients with the constants, Dy:

Dy = |8 2|

|2 -10|

Dy = (8 * -10) - (2 * 2)

Dy = -80 - 4

Dy = -84

Now, we can find the values of x and y:

x = Dx / D

x = 42 / -42

x = -1

y = Dy / D

y = -84 / -42

y = 2

Therefore, the solution to the system of equations is x = -1 and y = 2.

Answer:

Step-by-step explanation:

To find the recommended daily amount of protein, we can set up a proportion using the given information:

30% of the recommended daily amount = 96 grams

Let "x" represent the recommended daily amount of protein. We can set up the proportion as:

30/100 = 96/x

To solve for x, we can cross-multiply and solve the equation:

30x = 100 * 96

30x = 9600

Dividing both sides by 30:

x = 9600 / 30

x ≈ 320

150 miles is the same as 150*5280 = 792000 feet, and one hour is equivalent to 60*60 = 3600 seconds. Now we divide 792000 feet by 3600 seconds to get the equivalent rate: 792000 ft/3600 sec = 220 ft/second. Now, we multiply the rate by 5 and get 1100 feet per 5 seconds. So, our answer is 1100 feet.

The amount of state tax Selina owes is $77.42.

To calculate the amount of state tax Selina owes, we need to follow the given information.

Selina's gross pay for two weeks is $840. We need to determine her federal tax contribution based on the provided tax table.

Looking at the federal tax table, we find that for a gross pay of $840, the federal tax withheld for 0 withholding allowances is $98.

Next, we calculate the state tax deduction, which is 21% of the federal tax contribution:

State tax deduction = 21% of $98

State tax deduction = 0.21 * $98

State tax deduction = $20.58

Finally, we subtract the state tax deduction from the federal tax contribution to find the amount of state tax Selina owes:

State tax owed = Federal tax contribution - State tax deduction

State tax owed = $98 - $20.58

State tax owed = $77.42

Therefore, the amount of state tax Selina owes is $77.42.

Answer:

f = 65

s = 144

t = 144

u = 77

Step-by-step explanation:

the sum of a triangles angles will always be 180

so we can subtract 37 and 78 from 180 to find f which is 65

in regards to s and t, the sum of those 4 angles will be 360, and we can assume the opposite sides of the angles are the same.

so the other side of the 36 angle will also be 36, so we subtract 36 and 36 from from 380 which gives us 288

then we divide it by 2 because we have 2 unknown angles that are the same size, then we get 144 for s and 144 for t

the sum of the angles of a polygon will always be 360

so we can subtract 86 and 53 and t (which we now know is 144) from 360 to find u

so u = 77
