Answer:

$y=2\frac{1}{7}$

Step-by-step explanation:

(y · 7) - 4 = 11

7y - 4 = 11

7y - 4 + 4 = 11 + 4

7y = 15

7y ÷ 7 = 15 ÷ 7

$y=2\frac{1}{7}$

What is the answer to this

Karolina [17]

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