Answer
r > -220
Solution
We start with the inequality:
r/22 > -10
Since 22 is a positive number, we can multiply both sides by 22 without changing the inequality direction:
r > -10 × 22
Performing the multiplication:
r > -220
Thus, the solution is:
r > -220

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!
