1.8(b-5.3)-4.2=5.8(b-2.3) help me please

Answers

The solution to the equation given as 1.8(b-5.3)-4.2=5.8(b-2.3) is b = -0.1

How to determine the solution to the equation

From the question, the equation is given as

1.8(b-5.3)-4.2=5.8(b-2.3)

Rewrite the equation properly

This is represented as follows

1.8(b - 5.3) - 4.2 = 5.8(b - 2.3)

Open the brackets in the above equation

So, we have

1.8b - 9.54 - 4.2 = 5.8b - 13.34

Collect the like terms in the equation

So, we have

1.8b - 5.8b = 9.54 + 4.2 - 13.34

Evaluate the like terms in the equation

So, we have

-4b = 0.4

Divide by -4

b = -0.1

Hence, the solution is b = -0.1

Answers

By SAS rule, triangle DAB is congruent to triangle DCB

Define congruency.

If two shapes are similar in size and shape, they are congruent. We can also state that if two shapes are congruent, then their mirror images are identical. If and only if two angles have equal measurements, they are said to be congruent. If and only if two segments have equal amounts of each, they are congruent. If and only if all of the corresponding angles and sides are congruent, two triangles are said to be congruent.

Given data

U2 L2 solutions of a graphed equationWhich point is not a solution to the equation 4y = 167A (4, 2)C. (2, 3)D. (5, 1.5)Question 1

Answers

(4,-2) does not lie on the line

Here, we want to select the point that is not a solution to the graphed line

What we have to do is just to susbtitute the value of x and y. If by aritjmetic operation, the result is 16, then the point lies on the line

We proceed as follows;

a) (4,-2)

-2(4) -4(-2)

-8+8 = 0

This lies on the line

b) (1, -4.5)

-2(1)-4(-4.5) = -2 + 18 = 16

This is not on the line

c) (-2,-3)

-2(-2)-4(-3) = 4 + 12 = 16

d) -2(-5)-4(-1.5)

= 10 + 6 = 16

As we can see, only the first point does not lie on the line

the sum of an integer and five times the next consecutive odd integer is -32. Find the value of the lesser integer

Answers

The value of the lesser integer is  a =  -7

How to find the value of the lesser integer?

Let an integer be = a

Let the next consecutive odd integer (b) = a+2

a + 5( b) = -32

a +5(a+2)= -32

a+ 5a +10 = - 32

6a = -32 -10

6a = -42

a = - 42 /6

a = - 7

   The integer a = -7

The next consecutive odd integer (b) = a+2

                                                              = -7 + 2

                                                           b  = -5

So, the value of the lesser integer  is a = -7

What is the equation of the line?The standard form of a line equation is ax + by + c = 0. The coefficients are a and b, the variables are x and y, and the constant term is c. It is a one-degree equation with variables x and y. The coordinates of a point on the line defined in the coordinate plane are represented by the values of x and y.

For the given question;

The equation of line in the standard form is given as;

Ax + By = C, where C = 24

Part a: Graph 1.

Locate two points lying on the line.

(4, 0) and (0, 3)

Answers

When the plane reaches an altitude of 2,000 ft temperature will be 59.3F

What is altitude?

The height of a thing above the surface of a planet or natural satellite, like the sea or land is known as altitude.A distance measurement between a reference datum and a point or object, typically in the vertical or "up" direction, is known as altitude, height, or depth.

Although the term "altitude" is frequently used to refer to a location's height above sea level, the term "elevation" is frequently preferred in the context of geography. The term "depth" often refers to vertical distance measurements taken in the "down" direction.

For every 1000 ft there is a drop of 1.2 Fahrenheit

∴ for 2000ft drop in temperature of 2×1.2=2.4F

Also the temperature on the ground is 61.7F

The temperature when the plane reaches 2,000 ft will be

What is Compound Interest ?

Compound interest, also known as interest on principal and interest, is the practice of adding interest to the principal amount of a loan or deposit. Reinvesting interest, or adding it to the lent capital rather than paying it out or seeking repayment from the borrower, results in interest being received on the principal amount plus previously collected interest in the next period.

Formula used,

A=P(1+r/n)^nt

A = ending amount

P = principal amount(beginning amount)

n = time period

r = rate of interest

Given,

A = $350000

p = $250000

r = 2.04% or 0.0204

n = 12 months

Now, put these values in given formula

350000 = 250000(1 + 0.0204/12)^12t

              = 250000 * 1.0017^12t

350000/250000 = 1.0017^12t

1.4 = 1.0017^12t

Take log on both the sides,

㏑(1.0017^12t) = ㏑(1.4)

12t * ㏑(1.0017) = ㏑(1.4)

12t * 0.0017 = 0.3365

t = 0.3365 / 0.0204

t = 16.5 years

Therefore, Shannon will take time 16.5 years to have $350000

Two easy steps can be used to determine the mean, or average, of a set of data: Add up all of the values to get the sum. Divide the total by the total number of values in the data collection. A data set's mean (average) is determined by summing all of the numbers in the set, then dividing by the total number of values in the set.

Let the initial amount on Jon's gift card be x dollars.

Jon pays $17 for a shirt using the gift card and the remaining balance was $31.

That is, the equation representing this is

x - 17 = 31

To solve this, we add 17 to both sides

x - 17 + 17 = 31 + 17

Which of the following equations could be used to determine different combinations of b bags of balloons and h packages of party hats that he could buy for a total of $24 A.) b+h=24
B.) (1.50+6.00)(b+h)=24
C.) 1.50b+6.00h=24
D.) 6.00b+1.50h=24

Please provide how you did it so I can understand​

Answers

Answer:

The answer is C.

Step-by-step explanation:

Since the party store charges $1.50 for each bag of balloons, the total price depends on how many bags of balloons Jimmy purchases. So to represent that amount we use the variable given, b. To represent that we can do 1.50b. If we substitute any positive number for b it could look something like this:

(1.50)(1) or 1.50 × 2.

In addition to this, they also sell packages for $6.00 each. We do the same as with the balloons and use the variable h to represent the number of packages Jimmy buys.

We already know that he spends $24 in total but we do not know how many of each item he bought. So we would represent the unit rate price × the variable (or the unknown number of items) of the balloons + the unit rate price and the unknown number of the party hats.

1.50b + 6.00h = 24.
