Question

A 84​-inch pipe is cut into two pieces. One piece is two times the length of the other. Find the length of the shorter piece.

Answer 1

Answer: 84/2=42, 42-12=28 42+12= 56 56+28=84

Explanation:

Answer 2

Let the short piece = x

Th longer piece would be 2x ( twice as long)

Now you have x + 2x = 84 inches

Simplify:

3x = 84

Divide both sides by 3:

X = 28

The shorter piece is 28 inches.
