m = 0.25
m = 0.4
m = 1
m = 4

Soo.. its 1.2 = -1.2?
EndersWorld:
1.2m=-1.2
RawlsK29:
Which is -1, so that cant be right. My teacher said that the answer is 0.25 but I have no idea how she got that.
EndersWorld:
Shadow... I’m getting -1 as a answer. What am I doing wrong?
Shadow:
You are forgetting the variable next to -2

3.2m=0.8 don’t forget the variable. Now.
EndersWorld:
Now, divide both sides by 3.8 and you get m=?
RawlsK29:
yeah sorry 3.2m = 0.8 ohhhh then I get 0.25
RawlsK29:
that makes much more sense
EndersWorld:
