Answer:
8 degrees Celsius is the answer
Explanation:
Since at 5 a.m. the temperature was -6 degrees and the temperature increased 2 degrees every hour until noon, you can subtract noon (12) by 5 to realize that 7 hours have passed. Now multiply 2 by 7 to get 14. This means that the total increase in temperature was 14 degrees Celsius.
Finally, add 14 to -6, and when you do that math, you will get an answer of 8.
