Question

An electrician cuts a 30 ft piece of wire into 2 pieces. One piece is 2ft longer than the other. How long are the pieces?

Answer 1

Length of short piece = x
Length of longer piece = x + 2
Given x + x + 2 = 30, 2x = 28, x=14
Pieces are 14ft and 16ft long

Answer 2

piece1: 14 feet

piece2: 16 feet

Explanation:

piece1: x

piece2: x + 2

x + x + 2 = 30

2x + 2 = 30

2x = 28

x = 14

piece1: x = 14

piece2: x + 2 = 14 + 2 = 16
