Question

Pls help I need a good grade

Answer 1

Explanation:

13).
`-(q)/(7)\geq -1`

`(q)/(7)\leq 1`

`((q)/(7)* 7)\leq (1* 7)`

q ≤ 7

14). -12x < 60

12x > -60

`(12x)/(12)>(-60)/(12)`

x > -5

15). 5 > z - 3

5 + 3 > z - 3 + 3

8 > z

16). 0.5 ≤
`(y)/(8)`

0.5 × 8 ≤
`(y)/(8)* 8`

4 ≤ y

Now we can draw these inequalities on a number line.
