Problema Solution
Two lengths of board total 48 in. If one board is 17 in. Shorter than the other, find the length of each board
Answer provided by our tutors
let
l1 = the length of the first board
l2 = the length of the second board
two lengths of boards total 48 in
l1 + l2 = 48
one board is 17 in shorter than the other
l1 = l2 - 17
by solving the system of equations
l1 + l2 = 48
l1 = l2 - 17
we find
l1 = 15.5 in
l2 = 32.5 in
the lengths of each board are 15.5 in and 32.5 in.
