Answer:

r = \frac{3t}{t-1}

Step-by-step explanation:

t = \frac{r}{r - 3}

Cross multiply,

t(r - 3) = r

tr - 3t = r

     tr  = r + 3t

 tr - r = 3t

 r(t -1) = 3t

 r = \frac{3t}{t-1}

Answer:

r = 3t/(t - 1)

Step-by-step explanation:

t = r/(r - 3)

t(r - 3) = r

tr - 3t = r

tr = r + 3t

tr - r = 3t

r(t - 1) = 3t

r = 3t/(t - 1)

|30 - 32| ≤ 8

|-2| ≤ 8

2 ≤ 8

            Hope this helps! :)
