Question

If an equation for d is d = rt, what is an equation for r (solve for r)?
A. r = dt, d ≠ 0
B. r = d/t, t ≠ 0
C. r = t/d, d ≠ 0
D. t = d/r, r ≠ 0

Answer 1

you have d=rt, then the opposite of multiplication is division therefore to isolate the r, you divide by t, then you have d/t = r

Answer 2

so, B?
