Answer:
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
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
