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
