b. Commutative Property of Addition Reason: There is no multiplication used
2. a. 60 Reason: 36 + 24 = 60
3. b. 3d + 9 Reason: Simplification and combining like terms :)
4. b. 4,-1 Reason: Coefficients are the numbers in front of variables
5. b. 36m + 9 Reason: Just use distributive property (multiply 9 into both terms inside parenthesis)
6. b. 95.488 Reason: b = 165.288 - 39.7 - 30.1
7. The question is cut off, unanswerable
8. c. 5a, -3a Reason: Like terms are things you can combine. So technically the answers could be b. and c. but just go with c. because they have variables.
9. b. 16 Reason: just add 4 to both sides to get the "a" by itself
