Quizplus · Accepted Answer

To solve the given division problem, we first simplify the divisor $\frac{8y - 80}{64}$ by factoring out 8 from the numerator and simplifying the fraction to get $\frac{y - 10}{8}$. Then, we rewrite the division as multiplication by the reciprocal of the divisor: $\frac{(y - 10)^2}{8} \times \frac{8}{y - 10}$. Simplifying this, we cancel out one $y - 10$ term and the 8s, leaving us with $y - 10$.
