Question

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

Answer 1

\[19\le5x+4\le24\]

Answer 2

This is the basic set up of the inequality

Answer 3

Yeah..

Answer 4

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

Answer 5

Which would leave us with 15 5x and 20

Answer 6

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

Answer 7

yes

Answer 8

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

Answer 9

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

Answer 10

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

Answer 11

OH! is that my answer??

Answer 12

yes good job!!

Answer 13

Thank you!!! :D

Answer 14

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

Answer 15

Okay(: Thanks you bunches.

Answer 16

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.

Answer 17

Yeah no problem.
