Answer:
23. 8n - 9
24. 55 - 45n
25. 69a - 10
26. -30m + 33
27. -4 + 96x
28. -8n + 26
29. -25b - 20
30. -71n - 9
Step-by-step explanation:
23. -2n - 9 + 10n
Collect like terms
= 8n - 9
24. 10 - 45n + 45
Collect like terms
= 55 - 45n
25. 9a + 60a - 10
Collect like terms
= 69a - 10
26. -54m + 27 + 6 + 24m
Collect like terms
= -30m + 33
27. -10 + 90x + 6x - 60
Collect like terms
= -4 + 96x
28. -10n + 20 + 2n + 6
Collect like terms
= -8n + 26
29. -30b - 30 + 5b + 10
Collect like terms
= -25b - 20
30. -7n - 21 - 8 - 64n
Collect like terms
= -71n - 9
Step-by-step explanation:
(−3)(+8)
Answer:
x = -8
Step-by-step explanation:
g(x) = 8x + 2
given: g(x) = 8x + 2 = -62
8x = -62 -2
8x = -64
x = -8
Answer:
its 5
