Question

he temperature in Alaska one morning was -42°F. By 2:00 P.M., the temperature increased by 16 degrees. Write a number sentence and solve to find out what the afternoon temperature was. The number sentence can be written as: -42°F + 16°F = ? Now, simply add these values together: -42 + 16 = -26°F

Answer 1

The afternoon temperature in Alaska was -26°F. The initial temperature of -42°F increased by 16°F, resulting in a final temperature of -26°F.

Step-by-step explanation:

The given number sentence is: -42°F + 16°F = ?. To find the afternoon temperature, add the initial temperature (-42°F) to the increase in temperature (+16°F). Mathematically, this can be represented as -42 + 16 = -26°F. The negative sign indicates a below-freezing temperature.

In the explanation, it's important to understand that when the temperature increases, we add the positive change to the initial temperature. In this case, starting at -42°F, the temperature increased by 16°F. Adding these values -42 + 16 gives us the final temperature of -26°F. This negative value indicates a cold afternoon in Alaska.

In colder regions like Alaska, temperatures often experience significant fluctuations. The negative result reinforces the cold nature of the weather. It's crucial to pay attention to the sign in such mathematical operations as it reflects the direction and magnitude of the change. In this context, the negative sign signifies a decrease in temperature, resulting in a final afternoon temperature of -26°F.
