The answer's 22.4. You have to divide 548.8 miles by 24.5 gallons.
Answer:
m=21
Step-by-step explanation:
34=2m-8
34+8=2m
42=2m
42 / 2=21
m=21
The length of shortest piece is 12 inches and length of middle piece is 18 inches and length of longest piece is 20 inches
<em><u>Solution:</u></em>
Let, "x" be the shortest piece
<em><u>The middle piece is 6 in. longer than the shortest piece</u></em>
Middle piece = 6 + x
<em><u>The shortest piece is 8 in. shorter than the longest piece</u></em>
Longest piece = 8 + x
<em><u>A boy purchased a party-length sandwich 50 in. long</u></em>
Therefore, total length = 50
Shortest piece + Middle piece + Longest piece = 50
x + 6 + x + 8 + x = 50
14 + 3x = 50
3x = 50 - 14
3x = 36
Divide both the sides by 3
x = 12
Therefore,
shortest piece = 12
middle piece = 6 + x = 6 + 12 = 18
longest piece = 8 + x = 8 + 12 = 20
Thus, length of shortest piece is 12 inches and length of middle piece is 18 inches and length of longest piece is 20 inches
