Answer 1

The temperature in Madison, Wisconsin at noon was 21°C. The temperature in Anchorage, Alaska at sunrise was -6°C.

Step-by-step explanation:

Part A:

To find the temperature in Madison, Wisconsin at noon, we need to add the increase in temperature to the temperature at sunrise. The temperature increased by 23°C, so we can add that to the sunrise temperature of -2°C:

-2°C + 23°C = 21°C

Therefore, the temperature in Madison, Wisconsin at noon was 21°C.

Part B:

To find the temperature in Anchorage, Alaska at sunrise, we need to multiply the temperature at sunrise in Madison, Wisconsin by 3. The temperature at sunrise in Madison, Wisconsin was -2°C, so we can multiply that by 3:

-2°C × 3 = -6°C

Therefore, the temperature in Anchorage, Alaska at sunrise was -6°C.
