Answer:
[tex]23^{\circ}F[/tex]
Step-by-step explanation:
We have been given that the temperature at 8:00 a.m. was –6°F. By 4:00 p.m. the temperature was 17°F. We are asked to find the change in temperature from 8:00 a.m. to 4:00 p.m.
The change in temperature would be final temperature minus initial temperature.
[tex]\text{The change in temperature}=17^{\circ}F-(-6^{\circ}F)[/tex]
[tex]\text{The change in temperature}=17^{\circ}F+6^{\circ}F[/tex]
[tex]\text{The change in temperature}=23^{\circ}F[/tex]
Therefore, the change in temperature from 8:00 a.m. to 4:00 p.m. is 23 degree Fahrenheit.
