A. c=-9*** My Answer
B. c=-36
C. c=9
D. c=36

Answer 1

There's a problem here, look at your signs.

Answer 2

What happens when you divide a negative by a negative?

Answer 3

you get a negative

Answer 4

No you get a positive, it's like multiplication when you multiply 2 negatives you get a positive.

- x - = +
-/- = +

Answer 5

Also, you can check your answer

-2c=-18

-2(-9)=-18 ... replace c with -9 (since you claim c = -9)

18 = -18 .. as iambatman is saying, negative times negative = positive


The equation is false. So c = -9 is not the solution to -2c=-18

Answer 6

Ok I got C. c=9 as my answer

Answer 7

much better, let's check that


-2c=-18

-2*(9)=-18 ... plug in c = 9

-18 = -18 ... it works now
