Question

At noon the temperature was 37°F. At 7 AM the temperature was 17°F colder. Thetemperature at 7PM was 4 Degrees Fahrenheit warmer than at 7 AM What was the temperature at7 PM?

Answer 1

The temperature at 7 PM is:

`24^(\circ)F`

Step-by-step 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`
