Answers

15,640 * 7.2% = 1,126.80 Sales tax

Total cost:
cost of an item: 15,640 - 2,500 = 13,140.00

The perimeter of a rectangle is 38 inches. If the length of the rectangle is 14 inches, which equation could be used to find the width, x?

Answers

Perimeter, P = 2*(L + W)

Length, L = 14, Width = x

 P = 2*(L + W)

38 = 2*(14 + x).

2*(14 + x) = 38,  is the equation used to find x.

Let's go ahead and solve for x, though the question did not ask us to solve it. 

 14 + x = 38/2

  14 + x = 19

       x = 19 - 14

        x = 5

Width is 5 inches.

Answer:        x = 19 - 14

so 5 inch

I had the question

Brody wants to build a model ship. He has already saved $30 for the materials and plans. The materials costs $24.89 and the plans cost $8.29. Brody says he has to save $5.11 more to pay for the materials and plans.

Which explanation explains whether Brody is correct or not?

A.
Brody is correct.

Estimation: 30.00 – 8.29 is about 22.
$22 + $25 = $47.
Brody needs to save about $47 more.

B.
Brody is not correct.

Estimation: 24.89 – 8.29 is about 17.
$30 – $17 = $13.
Brody needs to save about $13 more.

C.
Brody is not correct.

Estimation: 24.89 + 8.29 is about 33.
$33 – $30 = $3.
Brody needs to save about $3 more.

Answers

The correct answer is C., because they did the steps correctly.

A is not right because you're not supposed to add the cost ( $25 ) to the money saved for the expenses. ( it would be $22 since you already minus out the 8.29 cost )

B is also not correct because you do not subtract the cost from another cost. ( 24.89 - 8.29 )

Hope I helped!
