Question

At 7:00 a.m., the temperature was -3°F. At 6:00 p.m., the temperature was

9°F greater than the temperature at 7:00 a.m. and had fallen 4°F from the
temperature at noon.
Which of the following can be used to determine the
temperature at noon in degrees Fahrenheit?
A) -3 + 9 + 4
B) -3 + 9 + (-4)
C) -3 + (-9) + 4
D) -3+ (-9) + (-4)

Answer 1

A) -3 + 9 + 4

Explanation:

We are given the following information: At 7:00 a.m., the temperature was -3°F. At 6:00 p.m., the temperature was 9°F greater than the temperature at 7:00 a.m. This means the temperature at 6:00 p.m. is calculated as -3 + 9.

We know this last temperature is 4°F less than the temperature at noon, thus the temperature at noon is calculated as -3 + 9 + 4

A) -3 + 9 + 4
