For 1-6, solve each equation for x. (Lesson 4.1 and 4.2)
1. ! − 1.2 = −6.8 2. 0.6! = 0.78
3. 4! − 8 = 16 4. !
"# − 5 = 11
5. 48! − 18 = 174 6. −3! − 10 = −46
It

For 7-10 simplify each expression by combining like terms. (Unit 3)
7. (8! − 16) + (−22! − 4)=
8. (5! − 2) − (8! − 4)=
9. 2(6! + 3) + (−4! + 8)=
10. (16! + 5) + (9! − 2) + 3(−! + 3)
