Question

A board 18 feet long is cut into three pieces. the second is twice as long as the first piece and the third piece is 3 feet longer than the second. how long is each piece

Answer 1

3 ft

6 ft

9 ft

Explanation:

Set up your equation;

18=x+2x+2x+3

simplify;

5x+3=18

18-3= 15

5x=15

15/5=3

x=3

Then plug everything in;

3(2)=6

3(2)+3=9
