Answer:

4 1/2

Step-by-step explanation:

7 5/6 - 3 1/3

changing to improper fractions;

47/6 - 10/3 LCM = 6

(47 - 20)/6

27/6 = 9/2 = 4 1/2.

Answer:

8,5

Step-by-step explanation:

5*8-2y=30

40-30=2y

10=2y

y=10/2

y=5

Answer: The answer is 5!

Answer:

(4,5)

Step-by-step explanation:

Since you move right 4 from the origin, then your x value would increase by 4, and since you're moving 5 units up from the origin, then your y value would increase by 5

Answer:

She was driving for 5 hours

Step-by-step explanation:

Let us solve the question

∵ Kate begins with 16 gallons of gas in her car

∵ Her car burns 3 gallons of gas each hour

→ That means the rate of burn of the gas is 3 gallons per hour

∵ She ends her road trip with 1 gallon of gas left in the tank

→ That means she used the difference between 16 and 1 gallons

∴ The number of gallons she used = 16 - 1 = 15 gallons

→ By using the ratio method

→ Gallon  :  hour

→  3          :  1

→  15        :  x

→ By using cross multiplication

∵ 3 × x = 15 × 1

∴ 3x = 15

→ Divide both sides by 3

∴ x = 5

∵ x represents the number of hours of her trip

∴ She was driving for 5 hours

Answer:

B. c =14 v = 4 are a pair of solutions to the equation.

E. If 20 cars go, no vans are needed.

F. 8 vans and 8 cars are numbers that meet the constraints in this situation.

Step-by-step explanation:

Volunteer drivers are needed to bring 80 students to the championship baseball game. Drivers either have cars, which can seat 4 students, or vans, which can seat 6 students. The equation

4 c + 6 v = 80

We are to find what can transport exactly 80 students.

We compare the options till we get our correct answer.

A. If 2 cars go, then 2 vans are needed.

4 c + 6 v = 80

c = number of cars needed

v = number of vans needed

Hence,

4(2) + 6(2)

8 + 12 ≠ 80

20≠ 80

Option A is wrong

B. c =14 v = 4 are a pair of solutions to the equation.

4 c + 6 v = 80

c = number of cars needed

v = number of vans needed

Hence,

4(14) + 6(4) = 80

56 + 24 = 80

80 = 80

Option B is correct

C. If 6 cars go and 11 vans go, there will be extra space

4 c + 6 v = 80

c = number of cars needed

v = number of vans needed

Hence,

4(6) + 6(11)

24 + 66

110 > 80

Option C is wrong, there would be no space left

D. 10 cars and 8 vans isn't enough to transport all the students.

4 c + 6 v = 80

c = number of cars needed

v = number of vans needed

Hence,

4(10) + 6(8)

40 + 48

88 > 80

Option D is wrong

E. If 20 cars go, no vans are needed.

4 c + 6 v = 80

c = number of cars needed

v = number of vans needed

Hence,

4(20) + 6(0) = 80

80 + 0 = 80

80 = 80

Option E is correct

F. 8 vans and 8 cars are numbers that meet the constraints in this situation.

4 c + 6 v = 80

c = number of cars needed

v = number of vans needed

Hence,

4(8) + 6(8) = 80

32 + 48 = 80

80 = 80

Option F is correct

Therefore the statements in options B, E and F are the only correct statement for the equation 4 c + 6 v = 80

Answer:

dilation

Step-by-step explanation:

Dilation is the only one of the options in which the figure can change size. The angles stay the same

The solution is: Dilation is the transformation which preserves angle measures, but not segment lengths.

Here, we have,

we know that,

Transformation is the movement of objects in coordinate plane.

A function f will map a set X to itself. f:X→X.

Dilation is a transformation that produces an image of the same shape as the original but of different size.

In dilation angle measures are preserved where as lengths of segments are not preserved.

so, we get,

Dilation is the only one of the options in which the figure can change size. The angles stay the same.

Hence, The solution is: Dilation is the transformation which preserves angle measures, but not segment lengths.

Answer:

x = [tex]\frac{11}{3}[/tex]

Step-by-step explanation:

Given

4(2 - 6x) = - 80 ( divide both sides by 4 )

2 - 6x = - 20 ( subtract 2 from both sides )

- 6x = - 22 ( divide both sides by - 6 )

x = [tex]\frac{-22}{-6}[/tex] = [tex]\frac{11}{3}[/tex]

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

Given:

x and y are both differentiable functions of t.

[tex]4x^2+3y^3=28[/tex]

[tex]x=-1\text{ and }\dfrac{dy}{dt}=8[/tex]

To find:

The value of [tex]\dfrac{dx}{dt}[/tex].

Solution:

We have,

[tex]4x^2+3y^3=28[/tex]       ...(i)

At x=-1,

[tex]4(-1)^2+3y^3=28[/tex]

[tex]4+3y^3=28[/tex]

[tex]3y^3=28-4[/tex]

[tex]3y^3=24[/tex]

Divide both sides by 3.

[tex]y^3=8[/tex]

Taking cube root on both sides.

[tex]y=2[/tex]

So, y=2 at x=-1.

Differentiate (i) with respect to t.

[tex]4(2x\dfrac{dx}{dt})+3(3y^2\dfrac{dy}{dt})=0[/tex]

Putting x=-1, y=2 and [tex]\dfrac{dy}{dt}=8[/tex], we get

[tex]4(2(-1)\dfrac{dx}{dt})+3(3(2)^28)=0[/tex]

[tex]-8\dfrac{dx}{dt}+9(4)(8)=0[/tex]

[tex]-8(\dfrac{dx}{dt}-9(4))=0[/tex]

Divide both sides by -8.

[tex]\dfrac{dx}{dt}-36=0[/tex]

[tex]\dfrac{dx}{dt}=36[/tex]

Therefore, the value of [tex]4x^2+3y^3=28[/tex] is 36.

Answer:

To multiply decimals, first multiply as if there is no decimal. Next, count the number of digits after the decimal in each factor. Finally, put the same number of digits behind the decimal in the product.

Step-by-step explanation:

Example: Multiply 0.25 by 0.2

0.25 × 0.2. multiply without decimal points:

25 × 2 = 50. 0.25 has 2 decimal places,

Answer:

x < [tex]\frac{7}{12}[/tex]

Step-by-step explanation:

Move all terms not containing X to the right side of the inequality.

Make the addition sign the opposite, which is subtraction.

5/6 - 1/4 = 7/12

The < is still the same, so after the X is alone, make it an inequality.

x < [tex]\frac{7}{12}[/tex] is the answer.
