To evaluate each expression when a=11, b=8, and c=-6, simply substitute the given values into the expression and perform the necessary mathematical operations. Here's how to get the answer to each expression:
17. a - 17
Substitute a = 11:
11 - 17 = -6
18. 10 - b
Substitute b = 8:
10 - 8 = 2
19. -30 - c
Substitute c = -6:
-30 - (-6) = -30 + 6 = -24
20. b - a
Substitute a = 11 and b = 8:
8 - 11 = -3
22. c - b
Substitute b = 8 and c = -6:
-6 - 8 = -14
23. b - c + a
Substitute a = 11, b = 8, and c = -6:
8 - (-6) + 11 = 8 + 6 + 11 = 3
24. b - c - a
Substitute a = 11, b = 8, and c = -6:
8 - (-6) - 11 = 8 + 6 - 11 = 3
25. c - a - b
Substitute a = 11, b = 8, and c = -6:
-6 - 11 - 8 = -6 - 19 = -25
28. c - a + b
Substitute a = 11, b = 8, and c = -6:
-6 - 11 + 8 = -6 - 3 = -9
