Question

the temperature at 5 p.m. was 84°f. by 6 a.m., the change in temperature was -37°f. which estimate is closest to the temperature at 6 a.m.?

Explanation:

Step1: Recall temperature - change formula

The formula for finding the initial temperature is $T_{initial}=T_{final}-\Delta T$, where $T_{final}$ is the final temperature, $\Delta T$ is the change in temperature.

Step2: Identify given values

We know that $T_{final} = 84^{\circ}F$ and $\Delta T=- 37^{\circ}F$.

Step3: Calculate the initial temperature

Substitute the values into the formula: $T_{initial}=84-(-37)$. Using the rule that subtracting a negative is the same as adding a positive, we have $T_{initial}=84 + 37=121^{\circ}F$.

Answer:

$121^{\circ}F$
