    Part a) The temperature at noon was - 3°F

    Part b) The temperature at 3:00 pm was + 2°F

    Part c) The temperature at 11:00 pm was - 6°F (the temperature is negative)

    Step-by-step explanation:

    The complete question is

    When Leo woke up he saw that the temperature was - 8°F. By noon the temperature has increased 5°F. Part a) What was the temperature at noon?

    Part b) By 3:00 pm, the temperature increased by another 5 degrees Fahrenheit was the temperature at 3:00 pm positive or negative?

    Part c) By 11:00 pm, the temperature had dropped 8°F. Was the

    temperature at 11:00 PM positive or negative? Explain.

    Part a) we know that

    You can use a number line to adds the numbers

    -8+5=-3°F

    therefore

    The temperature at noon was - 3°F

    Part b) we know that

    the temperature increased by another 5 degrees

    You can use a number line to adds the numbers

    -3+5=+2°F

    therefore

    The temperature at 3:00 pm was + 2°F

    Part c) we know that

    the temperature had dropped 8°F

    You can use a number line to adds the numbers

    2-8=-6°F

    therefore

    The temperature at 11:00 pm was - 6°F

    so

    The temperature is negative
