Question

the temperature in a town is 23.1°f during the day and - 19.3°f at night. find the difference in the temperatures. the difference in temperature is °f.

Explanation:

Step1: Set up the subtraction

To find the difference between the two temperatures, we subtract the night - time temperature from the day - time temperature. The formula is $T_{diff}=T_{day}-T_{night}$, where $T_{day} = 23.1^{\circ}F$ and $T_{night}=- 19.3^{\circ}F$. So we have $23.1-(-19.3)$.

Step2: Simplify the subtraction

Subtracting a negative number is the same as adding its positive counterpart. So $23.1-(-19.3)=23.1 + 19.3$.

Step3: Perform the addition

$23.1+19.3 = 42.4$.

Answer:

$42.4$
