I'm not getting my homework done for me, I have the answers, I just need taught how to do these for my exam tomorrow! Pleasee help :/
1. Mofor make a trip to his cabin of the lake and back. The trip there took three hours andthe trip back took two hours. He averaged 10 mph faster on the return trip than on the outbound trip. Find Mofor's average speed on the outbound trip.
2. Perry left the hospital and drove north at an average speed of 28mph. Lea left three hours later and drove in the same direction but with an average speed of 70 mph. Find the number of hours Perry drove before Lea caught up.
3. What percent of 65 is 19.2?
4. What is 44% of 61?
5. 95% of 101.1 is what?
6. (solve) n/4 = -15/2
7. (solve) 20 + 8x = -(-x + 8)
8. (solve) -8(4b-6) - 4b = -36 -8b
9. (simplify) (6+ 2n^2 - 3n^4) - (8n^2 + 6 -7n)
10.(factor) 5m^2 - 10m -15
11. (factor) 7m^2 + 28 = -35m
12. (factor) x^2 = 32 + 4x
13. (factor) n^2 = -4n
14. (factor) p^2 + 20 = -9p
15. (evaluate) 49 - 37 + (-37)
16. (evaluate) (-49) - (22) - (-12)
17. (evaluate) (-4) - (4 - 12/-6)
