Answer:

C.  The x-terms are the same, and the constant terms are the same.

Step-by-step explanation:

Solve for x:

7 (x - 4) = 8 (x + 8)

Hint: | Write the linear polynomial on the left-hand side in standard form.

Expand out terms of the left hand side:

7 x - 28 = 8 (x + 8)

Hint: | Write the linear polynomial on the left-hand side in standard form.

Expand out terms of the right hand side:

7 x - 28 = 8 x + 64

Hint: | Move terms with x to the left-hand side.

Subtract 8 x from both sides:

(7 x - 8 x) - 28 = (8 x - 8 x) + 64

Hint: | Combine like terms in 7 x - 8 x.

7 x - 8 x = -x:

-x - 28 = (8 x - 8 x) + 64

Hint: | Look for the difference of two identical terms.

8 x - 8 x = 0:

-x - 28 = 64

Hint: | Isolate terms with x to the left-hand side.

Add 28 to both sides:

(28 - 28) - x = 28 + 64

Hint: | Look for the difference of two identical terms.

28 - 28 = 0:

-x = 64 + 28

Hint: | Evaluate 64 + 28.

64 + 28 = 92:

-x = 92

Hint: | Multiply both sides by a constant to simplify the equation.

Multiply both sides of -x = 92 by -1:

(-x)/(-1) = -92

Hint: | Any nonzero number divided by itself is one.

(-1)/(-1) = 1:

Answer: x = -92

250cm^2

To find the area of shape B we need to find the factor by which you multiply to get from 12 to 15. To find this we divide 15 by 12 to get 1.25. We now multiply the area of shape A (200) by the factor 1.25 to get the answer. The answer is 250cm^2.

Hope this helps! Please make me the brainliest, it’s not necessary but appreciated, I put a lot of effort and research into my answers. Have a good day, stay safe and stay healthy.

Usimov [2.4K]
Less than 3 is about 10.75% and greater than 13 is about 6.18%.

To find these percents, you need to find the z-score for each value. Then, use your table to find the correct percent. Be sure to find the side above 13 when you use your chart.

For less than 3:
(3 - 7.45) / 3.6 = -1.24 = The percent below this is 0.1075

For greater than 13:
(13 - 7.45) / 3.6 = 1.54 = The percent above this is 0.0618

givi [52]

Answer:

  • 1) 4812 students
  • 2) 763 pounds
  • 3) $30906.76

Step-by-step explanation:

1)

  • Initial number = 2988
  • Rate of increase = 10%

<u>Number of students after 6 years:</u>

  • a_6 = 2988(1+0.1)^{6-1} = 4812

2)

  • Initial number = 1200
  • Rate of decrease = 14%

<u>Amount of gold after 4 years:</u>

  • a_4=1200(1-0.14)^3 = 763

3)

  • Initial number = 28000
  • Rate of increase = 2.5%

a)

<u>Salary after n years:</u>

  • a_n=28000(1+0.025)^{n-1} = 28000*1.025^{n-1}

b)

<u>Salary in the 5th year:</u>

  • a_5=28000*1.025^4 = 30906.76
