Answer 1

@bobobox

Take this: −13 > −5x + 2 > −28

Add -2 -2 -2 -2
--------------------------------

What do you get?

Answer 2

That looks very intimidating
@Directrix

Answer 3

-13 - 2 =what

Answer 4

11

Answer 5

or -15?

Answer 6

-13 - 2 = - 15

Answer 7

okay, bare with me hear I'm clueless

Answer 8

What are these:

2 -2 =

-28 - 2 =

Answer 9

0
and
-30?

Answer 10

Right.

Answer 11

okay... I promise I will medal

Answer 12

−13 > −5x + 2 > −28
-2 -2 -2
------------------------
-15 > -5x > -30

is what we have so far.

Answer 13

okay

Answer 14

Now, it is time to divide by -5

Answer 15

-15 divided by - 5 =

-5x divided by - 5 =

-30 divided by -5 =

Answer 16

-3
-x?
-6

Answer 17

A negative divided by a negative is positive. You have sign-us trouble.

Answer 18

I have algebra troubles not just with signs

Answer 19

Don't be negative. Just change the signs on your answers and post. Let's keep moving.

Answer 20

3
x
6

Answer 21

Good.

Now, these numbers are part of an inequality expression.

When you divide an inequality by a negative, then the direction of the inequality reverses.

So, our greater thans (>) are reversing to less thans (<) Hold on.

Answer 22

-15 > -5x > -30

becomes

3 < x < 6

That is what we have to graph or describe.

Look at your options.

Do you see anything with a 2 and a 6 in it.

Answer 23

We are looking for numbers between 3 and 6 but not including 3 and 6.

Answer 24

if there is no equal signs, then your circles are open.
greater then (>) shaded to the right and less then (<) shaded to the left

Answer 25

number three
im not quite sure I see some with a line passsing by two but I just dont want to screw up

Answer 26

@bobo Let me look and see what I think.

Answer 27

3 < x < 6....break it down
3 < x....x is greater then 3

x < 6 .... x is less then 6

so we have x being greater then 3 and less then 6.....does that help ?

Answer 28

@bobobox I assume that the number line started out as the color brown/gold and that the graphs are in blue.

Answer 29

number line graph itself is gold and the options are blue... im pretty sure but hey anythings poosible

Answer 30

So, look for the blue segment with the "empty" circles at each end.

Answer 31

okay

Answer 32

the shading is blue

Answer 33

yup

Answer 34

@bobobox Which one do you see that looks like that?

Answer 35

the first option

Answer 36

yep....you got it

Answer 37

@bobobox Yes, that is correct.
