Answer: the shorter piece is 30 inches long.

the longer piece is 120 inches long.

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
