Answer 1

Ok, for this you simply have to rearrange the equation:
A = 5(b + 2c)
A / 5 = b + 2c
b + 2c = A / 5 (just switching things around to make it easier to follow)
2c = A / 5 - b
c = (A / 5 - b) / 2

I hope I helped!

Answer 2

wait what does the / mean? divide?

Answer 4

yes / means divide and babixz is correct with her answer c = (A/5 - b) /2 or it can also be written like this : c = (A/5)/2 - b/2
