Answer 2

Is there options?

Answer 3

20 < x + 8 less than or greater to 28

12 < x and x less than or greater to 20

A number line with an open circle on 12, shading to the left, and a closed circle on 20, shading to the right.

A number line with an open circle on 12, a closed circle on 20, and shading in between.

Answer 4

X is greater than 12, so an open circle
X is ALSO less than or equal to 20, so a closed circle
When there is an 'and' in the problem, you know that there should be shading in between.
