Question

inside kasis house, the temperature was 20°c. she stepped outside, where the temperature was 22°c cooler. which expression represents the temperature outside?

Explanation:

Step1: Define variables

Let \( T_{inside} = 20^\circ C \) (inside temperature), \( T_{outside} \) be the outside temperature. The outside is 22°C cooler, so we subtract 22 from the inside temperature.

Step2: Formulate the expression

The expression for outside temperature is \( T_{outside}=T_{inside} - 22 \). Substituting \( T_{inside} = 20 \), we get \( T_{outside}=20 - 22 \).

Answer:

The expression representing the outside temperature is \( 20 - 22 \) (in \(^\circ\text{C}\)), and the value is \(-2^\circ\text{C}\) (if calculating the value, but the expression is \(20 - 22\)).
