Math Problem Statement

At the beginning of the day, the temperature was -8°F. By noon, the temperature increased by 19°F. What was the temperature at noon?

Solution

The problem in the image asks:

"At the beginning of the day, the temperature was -8°F. By noon, the temperature increased by 19°F. What was the temperature at noon?"

To solve this, we need to add the temperature increase to the initial temperature:

Final temperature=8F+19F=11F\text{Final temperature} = -8^\circ F + 19^\circ F = 11^\circ F

Thus, the temperature at noon was 11°F.

Would you like a detailed explanation of how temperature changes work, or do you have any other questions?

Here are five related questions to expand this concept:

  1. What would the temperature be if it decreased by 19°F instead of increasing?
  2. How would you represent this problem on a number line?
  3. If the temperature increased by 25°F instead of 19°F, what would the noon temperature be?
  4. What is the difference between the starting and final temperatures?
  5. How would the calculation change if the temperature started at a positive value?

Tip: When adding or subtracting temperatures, treat them like any other integers!
