Q:

simplify the following algebra expression 3/4(1/2x-12)+4/5

Accepted Solution

A:
Answer:(1/40)·(15x + 392]Step-by-step explanation:I'm going to assume that you meant [3/4] · ( [1/2]x - 12) + 4/5.Carrying out the multiplication first, we get:[3/4] · [1/2]x + [3/4][-12] + 4/5.  This simplifies to:[3/8]x           + 9           + 4/5The LCD of this expression is (8)(5) = 40.  Thus, we have:40{ [3/8]x           + 9           + 4/5 }--------------------------------------------------                      40or:40{ [3/8]x           + 9           + 4/5 }--------------------------------------------------                      40which simplifies to:15x + 360 + 32        15x + 392---------------------- = -------------------           40                        40
