Question

the temperature on monday morning was -2 degrees fahrenheit. by noon it had warmed up to 5 degrees fahrenheit. how many degrees did the temperature change?

Explanation:

Step1: Identify the formula for temperature change

The temperature change is calculated by subtracting the initial temperature from the final temperature. So the formula is \( \text{Temperature Change} = \text{Final Temperature} - \text{Initial Temperature} \).

Step2: Substitute the given values

The initial temperature is \(-2\) degrees Fahrenheit and the final temperature is \(5\) degrees Fahrenheit. Substituting these values into the formula, we get \( 5 - (-2) \).

Step3: Simplify the expression

Recall that subtracting a negative number is the same as adding its positive counterpart. So \( 5 - (-2) = 5 + 2 = 7 \).

Answer:

The temperature changed by 7 degrees Fahrenheit.
