Answer:
length of shortest piece = 13 in
length of middle piece = 19 in
length of longest piece = 22 in
Step-by-step explanation:
Total length of sandwich = 54 inch
Let shortest piece = x
Middle piece = x+6
Longest piece = x+9
Add this pieces will make complete sandwich
x+(x+6)+(x+9) = 54
Solving
x+x+6+x+9 = 54
Combining like terms
x+x+x+6+9 = 54
3x + 15 = 54
3x = 54 -15
3x = 39
x = 13
So, length of shortest piece = x = 13 in
length of middle piece = x+6 = 13+6 = 19 in
length of longest piece = x+9 = 13+9 = 22 in
Substitution Method:
3x - 10 = 2x - 5
3x = 2x + 5
x = 5
Now solving for y:
y = 3x - 10
y = 3(5) - 10
y = 15 - 10
y = 5
(x, y) = (5, 5)
Check answer:
5 = 3(5) - 10
5 = 15 - 10
5 = 5
5 = 2(5) - 5
5 = 10 - 5
5 = 5
Since all of the equalities are true, (5, 5) is a true solution
0.628 is your answer. hope this helps
