Final answer:
The division expression to represent the change in temperature is 49°F ÷ 7. The average daily change in temperature is 7°F.
Step-by-step explanation:
To write a division expression to represent the change in temperature, we can divide the change in temperature (49°F) by the number of days (7). The division expression would be: 49°F ÷ 7.
To determine the average daily change in temperature, we divide the total change in temperature (49°F) by the number of days (7). The average daily change in temperature would be: 49°F ÷ 7 = 7°F.
Therefore, the average daily change in temperature is 7°F.
