4. \( \frac{x}{3}>132 \)

To solve the inequality \( \frac{x}{3}>132 \), start by multiplying both sides by 3 to eliminate the fraction: \( x > 396 \). This means any value of \( x \) greater than 396 will satisfy the inequality. To check for common mistakes, remember that when multiplying or dividing by a negative number, you must flip the inequality sign. However, in this case, you're multiplying by a positive number (3), so the direction of the inequality remains the same! Keep that in mind as you solve similar inequalities.
