Answer:
23 inches
Explanation:
Let us represent
First piece = x
Second piece = y
A 92-inch is cut into two pieces.
x + y = 92
One piece is three times the length of the other.
x = 3y
Find the length of the shorter piece.
Hence:
x + y = 92
x = 3y
3y + y = 92
4y = 92
y = 92/4
y = 23 inches
Solving for x
x + y = 92
x + 23 = 92
x = 92 - 23
x = 69 inches
The shorter piece is 23 inches long.
