Final answer:
To solve the inequality r/-3.5 > 9.1 for r, you multiply both sides by -3.5, which reverses the inequality sign, resulting in r < -31.85.
Step-by-step explanation:
To solve the inequality r/-3.5 > 9.1 for r, we can begin by multiplying both sides of the inequality by -3.5. Remember, when multiplying both sides of an inequality by a negative number, the direction of the inequality sign must be reversed. Therefore, we get:
r < -3.5 * 9.1
Now we multiply -3.5 by 9.1 to get:
r < -31.85
Thus, r must be less than -31.85 to satisfy the original inequality.
