Answer:
Let the short piece be x
The long piece is x + 6
The medium piece is 3x
Total
x + (x+6) + 3x = 11
5x + 6 = 11
5x = 11-6
x = 5/5
x = 1
Short piece is 1ft
Medium piece is 3ft
Long piece is 7ft
Shorter piece : 1
Medium piece: 3
Longest piece: 7
Step-by-step explanation:
11 = a + b + c
a =longest
b = medium
c = shortest
a = 6ft + c
b = 3 × c
* put that all into the equation
11= (6+c) + (3×c) + c
11 = 6 + c + 3c + c
5 = 5c
c = 1
