Question

A project calls for three pieces of wood. The longest piece must be twice the length
of the middle-sized piece. The shortest piece must be 10 in. shorter than the middle-
sized piece. If a board 70 in. long is to be used, how long can each piece be?

Answer 1

Answer:

70,35,25

Step-by-step explanation:

Let longest piece = a = 70

Let medium piece = b = 35

Let shortest piece = c = 25

a=2b

70=2b

35=b

c+10=b

c+10=35

c=25
