Answer:
15. -4
16. -2
17. 3
18. -3
19. 6
20. 0
21. 3
22. 4
23. 12
Step-by-step explanation:
f = -15
g = 5
h = -45
15. -20/ 5 = -4
16. 90/ -45 = -2
17. -45/ -15 = 3
18. (-15) (5) = -75/ 25 = -3
19. -15 - (-45) = 60/10 = 6
20. 5 - 5/ -1 = 0
21. - (15)/ 5 = 3
22. -45 - 3 (5)/ -15 = -60/ -15 = 4 [note: do parenthesis first)
23. -15 + (-45) = -60/ -(5) = 12
