9) \( \frac{r}{22}>-10 \)

To solve the inequality \( \frac{r}{22}>-10 \), you can multiply both sides by 22 (remember, since 22 is positive, the inequality direction remains the same). This gives you \( r > -220 \). This means that any value greater than -220 for \( r \) will satisfy the inequality! One common mistake with inequalities is forgetting to reverse the inequality sign when multiplying or dividing by a negative number. Always keep an eye on the sign; it can change everything! So, when you're working with inequalities, a little sign vigilance goes a long way!
