Question

1. $10 leq \frac{t}{-2}$

Explanation:

Step1: Multiply both sides by -2

When multiplying or dividing an inequality by a negative number, the inequality sign flips. So, multiply both sides of \(10 \leq \frac{t}{-2}\) by -2: \(10\times(-2) \geq t\)

Step2: Simplify the left side

Calculate \(10\times(-2)\), which is -20. So we get \(-20 \geq t\) or \(t \leq -20\)

Answer:

\(t \leq -20\)
