Problema Solution
A lumber company has contracted to cut boards into two pieces so that one piece is three times the length of the other piece. If a board is 12 feet long, what is the length of each piece after cutting?
Answer provided by our tutors
suppose one piece is x and the other is y
we get
x + y = 12
x = 3y
solving we get
4y = 12
y = 3
so x = 3*3 = 9
one piece is 9 ft and other is 3 ft
