Answer:
Step-by-step explanation:
Let us represent:
Short pieces = x
Middle pieces = y
Long pieces = z
A three foot long deli sandwich must be split into three pieces
x + y + z = 3
The middle piece is twice as long as the shortest piece
y = 2x
The shortest piece is 8 inches shorter than the longest piece.
x = z - 8
z = x + 8
We substitute
x + y + z = 3
x + 2x + x + 8 = 3
5x = 8 - 3
5x = 5
x = 5/5
x = 1
y = 2x
y = 2 × 1
y = 2
z = x + 8
z = 1 + 8
z = 7
How long should the three pieces be?
