Question

A pvc pipe is 125 in. in length and must be cut so that one piece is 15 in. longer than the other piece.

Find the length of each piece

Answer 1

55 and 70

Explanation:

Let x = the short piece

Let x+15 = the longer piece

x + x+ 15 = 125 Combine like terms

2x + 15 = 125 Subtract 15 from both sides of the equation

2x = 110 Divide both sides by 2

x = 55

This is the short side

x + 15

55 + 15

70

Answer 2

so the length of them are 77.5 and 47.5 in.
