Answer:
-9°F
Explanation:
The temperature at 6:00 a.m. = -12°F
The temperature increases by 1/2°F each hr.
Therefore, for 6 hours, we have an increase in temperature:
[tex]6\times\frac{1}{2}=3\degree F[/tex]Thus, the temperature, in degrees Fahrenheit at noon will be:
[tex]\begin{gathered} =-12\degree F+3\degree F \\ =-9\degree F \end{gathered}[/tex]
