What is r/15 > -3
-
the line is there for the greater than equal

I'm gonna do this 2 ways because I'm not sure what you mean about the line. I'm going to indicate greater than or equal to with >=.

1st I'll solve for

r/15 >= -3

multiply by 15 on each side

r >= -45

Next I'll solve for

r/15 >= 3
multiply 15 on each side

r >= 45

So depending on if that is a 3 or -3 that is how you would do it

So did I read the problem right?
