The shortest piece is 14 inches, middle piece is 19 inches and longest piece is 23 inches long.
Step-by-step explanation:
Let,
x be the shortest piece.
Therefore,
Middle piece = x+5
As shortest piece is 9 in shorter than longer piece;
Shortest piece = longest piece - 9
x = longest piece - 9
longest piece = x+9
Length of sandwich = 56 in
According to given statement;
Shortest piece + middle piece + longest piece = 56
[tex]x+(x+5)+(x+9)=56\\x+x+5+x+9=56\\3x+14=56\\3x=56-14\\3x=42[/tex]
Dividing both sides by 3;
[tex]\frac{3x}{3}=\frac{42}{3}\\x=14[/tex]
Shortest piece = 14 in
Middle piece = 14+5 = 19 in
Longest piece = 14+9 = 23 in
The shortest piece is 14 inches, middle piece is 19 inches and longest piece is 23 inches long.
