Question: Solve $2 < \frac{q-6}{5} \leq 7$
1. **State the problem:** Solve the compound inequality $$2 < \frac{q-6}{5} \leq 7$$ for $q$. 2. **Recall the rule:** To solve inequalities involving fractions, multiply all parts of the inequality by the denominator (if positive) to eliminate the fraction without changing inequality directions. 3. Multiply all parts by $5$ (positive, so inequality signs remain): $$2 \times 5 < \frac{q-6}{5} \times 5 \leq 7 \times 5$$ which simplifies to $$10 < q - 6 \leq 35$$ 4. Add $6$ to all parts to isolate $q$: $$10 + 6 < q - 6 + 6 \leq 35 + 6$$ $$16 < q \leq 41$$ 5. **Final solution:** $$\boxed{16 < q \leq 41}$$ This means $q$ is greater than $16$ and less than or equal to $41$.
