Question

Make r the subject of the formula t = r / r - 1​

Answer 1

r = t/t-1

Explanation:

Here, we want to make r the subject of the formula

what this mean is that we want to write the equation in terms of r

we have this as;

t = r/r-1

t(r-1) = r

tr - t = r

tr-r = t

r(t-1) = t

r = t/(t-1)
