Question

PLEASE HELP!
I have started it but I dont know how to finish

Answer 1

Answer: 4. First, a solid circle should be drawn on 13.5 since it is a value you get when you simplify the inequality and then you should draw a thick straight line to the greater side which is the right side of the number line

Explanation:

since you have already found the answers for 1,2 and 3 you are said to draw and show the inequality on a number line but first, you should make 'x' the subject of the inequality you have formed.

How 'x' is made the subject:

4x + 12
`\leq` 66

4x
`\leq` 66-12

`(4x)/(4) \leq (54)/(4)`

x
`\leq` 13.5 ← *so this is the one you should graph on your number line*

(since you can't draw it in the question form given to you I'll show you how it has to be drawn and I'll explain)

4. First a solid circle should be drawn on 13.5 since it is a value you get when you simplify the inequality and then you should draw a thick straight line along the number line to the greater side which is the right side of the number line

Answer 2

$13.5

Explanation:

$4x+ 12
`\leq` $66.

First, subtract 12 from both sides.

The 12 cancels out 12, so we are at: $4x
`\leq` $66.

Divide.

66 / 4 = 13.5.
