1. 8q+ 6 ; q = 2

1 answer:

6 0

1. 8q + 6 ; q = 2
= 8 ( 2 ) + 6
= 16 + 6
= 22 option D.

2. 9 + 4 ( -3 )
= 9 - 12
= -3 option A

3. 7 ( 4 ) - 7
= 28 - 7
= 21
option B

4. 10 - 3.2 ( 2 )
= 10 - 6.4
= 3.6 option B

5. 12 (1.5) + 4
= 18 + 4
= 22 option D.

6. 5w + 10 = 40
  5w = 30
w = 6 option A.

7. 4y - 12 = 60
  4y = 72
y = 18 option B

8 . 10k + 5 = 65
10k = 60
k = 6 option A

9. 2b - 15 = 33
2b = 48
b = 24 option C

10. 3d + 18 = 21
  3d = 3
d = 1 option B
