Question

write inequalities to represent the situations below.
the cargo of the truck weighs at most 2,900 pounds.
use w to represent the weight (in pounds) of the cargo.

the temperature inside the lab refrigerator is no more than 45 °f.
use t to represent the temperature (in °f) of the refrigerator.

Explanation:

Step1: Analyze the first situation

The phrase "at most" means the weight \( w \) can be equal to or less than 2900 pounds. So the inequality is \( w \leq 2900 \).

Step2: Analyze the second situation

The phrase "no more than" also means the temperature \( t \) can be equal to or less than 45 \( ^\circ \)F. So the inequality is \( t \leq 45 \).

Answer:

For the cargo weight: \( w \leq 2900 \)
For the refrigerator temperature: \( t \leq 45 \)
