A 150-inch pipe is cut into two pieces. One piece is four times the length of the other. Find the length of the shorter piece. The shorter piece is nothing inches long.

the shorter piece is 30 inches long.

the longer piece is 120 inches long.

Step-by-step explanation:

Let x represent the length of the shorter piece.

Let y represent the length of the longer piece.

A 150-inch pipe is cut into two pieces. It means that

x + y = 150- - - - - - - -1

One piece is four times the length of the other. It means that

y = 4x

Substituting y = 4x into equation 1, it becomes

x + 4x = 150

5x = 150

x = 150/5

x = 30

y = 4x = 4 × 30

y = 120

a) 15/7
