## TheNamesJesseKay 3 years ago Choose the correct inequality for: 19 is smaller than or equal to 5x+4 which is smaller than or equal to 24. A) 3 is smaller than or equal to x which is smaller than or equal to 7 B) 3 is smaller than or equal to x which is smaller than or equal to 5 C) 5 is smaller than or equal to x which is smaller than or equal to 4 D) 3 is smaller than or equal to x which is smaller than or equal to 4

\[19\le5x+4\le24\]

2. Monkeyball

This is the basic set up of the inequality

3. TheNamesJesseKay

Yeah..

4. Monkeyball

From there we can simplify because we want x by itself. So let's get rid of that positive 4 by subtracting 4....but that means we also have to subtract 4 from 19 and 24

5. TheNamesJesseKay

Which would leave us with 15 5x and 20

6. Monkeyball

\[19-4\le5x+4-4\le24-4\]

7. Monkeyball

yes

8. TheNamesJesseKay

Okay the what..? would you divide your 5 to get x alone?

9. Monkeyball

now lets get rid of that 5 from 5x....divide 5 all throughout

10. TheNamesJesseKay

Okay so now we have 3.. x.. and 4..

11. TheNamesJesseKay

12. Monkeyball

yes good job!!

13. TheNamesJesseKay

Thank you!!! :D

14. Monkeyball

but I hate leaving it like that this is how it looks like \[3\le x \le4\]

15. TheNamesJesseKay

Okay(: Thanks you bunches.

16. Monkeyball

In some questions you might get multiply answers with 3 and 4 so you have to be picky in order to get that one answer.

17. Monkeyball

Yeah no problem.
