(a) By noon, the temperature in Boston had risen by $13^{\circ} \mathrm{F}$. What was the temperature there at noon?
$\square$ ${ }^{\circ} \mathrm{F}$
(b) How much higher was the 6 a.m. temperature in Winnipeg
$\square$ ${ }^{\circ} \mathrm{F}$ higher
Solution
Solution Steps
Step 1: Determine the Temperature in Boston at Noon
The initial temperature in Boston is given as \(-5^\circ \mathrm{F}\). By noon, the temperature had risen by \(13^\circ \mathrm{F}\). To find the temperature at noon, we add the increase to the initial temperature:
\[
-5 + 13 = 8
\]
Final Answer
The temperature in Boston at noon was \(\boxed{8^\circ \mathrm{F}}\).
