Question

What is the answer to this

Answer 1

Answer:

t = $\frac{2r}{r+1}$

Step-by-step explanation:

Isolate the term with t by adding s to both sides

$\frac{2rs}{t}$ = rs + s = s(r + 1) ← common factor of s

multiply both sides by t to eliminate the fraction

ts(r + 1) = 2rs ( divide both sides by s(r + 1)

t = $\frac{2rs}{s(r+1)}$ ← cancel s on numerator/denominator

t = $\frac{2r}{r+1}$
