Answer 1

Answer:

The temperature at 7 PM is:

$24^{\circ}F$

Explanation:

Given;

At noon the temperature was 37°F.

$T_n=37^{\circ}F$

At 7 AM the temperature was 17°F colder;

$\begin{gathered} T_{AM}=(T_n-17)^{\circ^{}} \\ T_{AM}=(37-17)^{\circ} \\ T_{AM}=20^{\circ}F \end{gathered}$

The temperature at 7PM was 4 Degrees Fahrenheit warmer than at 7 AM;

$\begin{gathered} T_{PM}=T_{AM}+4 \\ T_{PM}=(20_{}+4)^{\circ}F \\ T_{PM}=24^{\circ}F \end{gathered}$

The temperature at 7 PM is;

$24^{\circ}F$
