Answer:
The length of the shorter piece is .
The length of the longer piece is .
Step-by-step explanation:
The five-step method is GUESS method.
Given:
Length of steel beam,
Length of longer piece is 1 foot longer than twice the shorter one.
Unknown:
Length of longer and shorter pieces of beam.
Let the length of shorter piece be feet.
Therefore, the length of longer beam is equal to
Evaluate:
Sum of lengths of longer and shorter pieces of beam is equal to the total length of beam. So,
Substitute and Solve:
Now, we have, .
Substitute 5 for for the lengths of shorter and longer pieces and solve for each. This gives,
Length of shorter piece =
Length of longer piece =
Therefore, the lengths of shorter and longer pieces are and
respectively.
