Just before sunrise, the temperature in degrees Fahrenheit was 13 degrees below zero. By 10 a.m. the temperature had risen 19 degrees. Which shows how to find the temperature in degrees Fahrenheit at 10 a.m.?
f 13 + 19 g -13 - 19 h -13 + 19 j 13 - 19
f 13 + 19
-13 + 19
= +6 by the way
It was below zero
Oops, you are correct. Thank you for catching my mistake!
The correct answer is:
h -13 + 19
= +6
To find the temperature in degrees Fahrenheit at 10 a.m., you need to add the rise in temperature to the initial temperature just before sunrise.
In this case, the initial temperature just before sunrise was 13 degrees below zero, which means it was -13 degrees Fahrenheit.
The rise in temperature from just before sunrise to 10 a.m. was 19 degrees.
So, to find the temperature at 10 a.m., you need to add the rise in temperature (19) to the initial temperature (-13).
Therefore, the correct expression is:
h) -13 + 19
When you calculate -13 + 19, the answer is 6 degrees Fahrenheit.
