Lets set the shorter piece equal to x
shorter = x
Now define the longer piece in terms of x
Given: longer piece is 4 times the shorter
longer = 4x
Ok we are told these two pieces were cut from a 10 ft board so we can write an equation to solve for x
short piece + long piece = 10 ft
x + 4x = 10
5x = 10
x = 2
Answer: short piece is 2 ft
Now use this to find the long piece
longer = 4x
4*2=8
Answer: long piece is 8 ft
Check answers:
short piece + long piece = 10 ft
2 + 8 = 10
