Can someone please answer this question please please answer it correctly and please show work please Please

answer:

Problem 8:  Option B, 10x - 8

Problem 9:  Option A, 9 degrees F

Problem 10:  Option A, x ≤ $6.69

Problem 11:  Option C, Four times the difference of two times a number less than 7

Problem 12:  Option B, 4

Problem 13: Option B, Table B

Problem 14:  Option D, 37.4

Step-by-step explanation:

Problem 8:  Simplify

4[(1/2x + 3) - (5 - 2x)]

4[1/2x + 3 - 5 + 2x]

4(5/2x - 2)

20/2x - 8

10x - 8

answer: Option B, 10x - 8

Problem 9:  Covert to inequality then solve

2n - 2 = 16

2n - 2 + 2 = 16 + 2

2n / 2 = 18 / 2

n = 9

answer:  Option A, 9 degrees F

Problem 10:  2x + 4.62 ≤ 18 Solve

2x + 4.62 - 4.62 ≤ 18 - 4.62

2x / 2 ≤ 13.38 / 2

x ≤ 6.69

answer:  Option A, x ≤ $6.69

Problem 11:  4(2n - 7) see what is same

answer:  Option C, Four times the difference of two times a number less than 7

Problem 12:  Convert words into an expression than solve

19.99x + 9.99 ≤ 100

19.99x + 9.99 ≤ 100 - 9.99

19.99x / 19.99 ≤ 90.01 / 19.99

x ≤ 4.5

answer:  Option B, 4

Problem 13:  See which is proportional

Table B

1/12 = 12

2/24 = 12

3/36 = 12

4/48 = 12

answer:  Option B, Table B

Problem 14:  To make a proportional table, the time / distance should be 0.29411764

11/3.4 = 3.23529411  -> Won't work

11/18.2 = 0.60439560 -> Won't work

11/23 = 0.47826086 -> Won't work

11/37.4 = 0.29411764 -> WORKS

answer:  Option D, 37.4

d (5 x (-20)) * (100 x (0.7))

step-by-step explanation:

5÷1/100 * -.7 *-20

copy dot flip

5*100 * -.7 *-20

rearrange

5*-20   * 100 *-.7

-100   *-70

7000

a

step-by-step explanation:

the denominator cannot be the same as one of the factors.

8 denominator times 2 denominator = 16

and 7 numerator time 11 = 77

77/16= 77/16 ( they cannot be further simplified)
