Answer 17

I think it is B

Answer 18

Multiply by -5

15 * -5 = ?

Answer 19

-75

Answer 20

Close, when you multiply or divide by a negative, the sign flips

Answer 21

what do you mean?

Answer 22

Oh I know that

Answer 23

but what did I do wrong?

Answer 24

instead of ≥ , the sign flips to ≤

Answer 25

Oh wait.... then it should be A

Answer 26

Yes

Answer 27

thanks... just one more & I will also fan you

Answer 28

Ok :)

Answer 29

here is a screen shot of it:)

Answer 30

for #1

add -2 + 8 = ?

Answer 31

+6

Answer 32

and then 6 * -2 = ?

Answer 33

-12

Answer 34

so x ≥ -12

it can be either B or C
which one do you think?

Answer 35

I think it is C.

Answer 36

No :/

Answer 37

why not? :(

Answer 38

Notice that it's greater than -12? so -11 and on is greater

Answer 39

oh... x is more than or = to -12 oops

Answer 40

i thought x was less than or = to -12

Answer 41

so it is B

Answer 42

so if #1 is B
then #4 is C because that's one of those sign that's less/greater than or equal to

Answer 43

oh ok

Answer 44

now #2

-11 + 8 = ?

Answer 45

-3

Answer 46

4 * -3 = ?

Answer 47

-12

Answer 48

so

x > -12

Answer 49

so A

Yep

Answer 52
