Simplify 8-5/8+1/2*6/9

Question

and
9c^3+7c-(3c^3-12+c)
and
Use set builder notation:
-14x-10(2p-3)=22-7(1-2p)

Answer 1

1. 8 5/8 + 1/2*6/9,
69/8 + 6/18,
69/8 + 1/3,
LCD = 24,
207/24 + 8/24 = 215/24 = 8 23/24.

2. 9c^3 + 7c -(3c^3 - 12 + c),
9c^3 + 7c - 3c^3 + 12 - c,
6c^3 + 6c + 12,
6(c^3 + c + 2).
