Final answer:
To represent the temperature changes in Chicago on that day, the addition expression would be 0 + (-7) + 10, indicating it started at zero, dropped by seven degrees, then rose to ten degrees Fahrenheit.
Step-by-step explanation:
The student's question involves creating an addition expression to represent the changes in temperature in Chicago on a particular day. On that day, the temperature started at zero degrees Fahrenheit at 1 am. It then decreased by seven degrees, and afterwards, increased until it was 10 degrees Fahrenheit. To write an addition expression for these temperature changes, we consider the initial temperature and both changes.
The initial temperature was 0 degrees Fahrenheit. It dropped by seven degrees, which is represented by (-7). Then, the temperature rose to 10 degrees Fahrenheit. Considering the temperature dropped first, we need to express the change from the initial zero degrees that is going below zero, and then the subsequent increase.
The correct expression to represent these changes is:
0 + (-7) + 10
This shows the temperature starting at zero, decreasing by seven degrees, and then increasing by a total of ten degrees.
