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.?
Start with the temperature before sunrise: -13°F. Add the temperature increase: +19°F.
-13°F + 19°F = +6°F
Therefore, the temperature at 10 a.m. was 6 degrees Fahrenheit.
To find the temperature in degrees Fahrenheit at 10 a.m., you need to add the rise in temperature to the initial temperature.
Given that the temperature just before sunrise was 13 degrees below zero (-13 degrees Fahrenheit), and it rose by 19 degrees, you can use the following formula:
Temperature at 10 a.m. = Initial temperature + Rise in temperature
Substituting the values, the equation becomes:
Temperature at 10 a.m. = (-13) + 19
Simplifying the equation:
Temperature at 10 a.m. = 6 degrees Fahrenheit
Therefore, the temperature at 10 a.m. is 6 degrees Fahrenheit.
