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 + 4/5
The LCD of this expression is (8)(5) = 40. Thus, we have:
40{ [3/8]x + 9 + 4/5 }
--------------------------------------------------
40
or:
40{ [3/8]x + 9 + 4/5 }
--------------------------------------------------
40
which simplifies to:
15x + 360 + 32 15x + 392
---------------------- = -------------------
40 40
