The length of a fabric needed for a dress is cut into two pieces. If the total length of the fabric is 200 inches and the shorter side is 10 inches less than half the length of the other fabric, what is the length of the shorter fabric?  Choose one:
A) 60  B) 140  C) 400  D) 200  E) 80
length one as L1, and length two as L2.   L1=(L2/2)-10 as eq.a   L1+L2=200 as eq.b   Substitute equation a into equation b, (L1/2)-10 +L1=200   Transpose like terms, (L1/2) + L1= 200 + 10   Get rid of fraction, L1+ L1*2= 400+20   reduces to 3*L1= 40, L1 results to 140.   Shorter fabric is (140/2)-10=
