Question

the temperature outside is - 9°f, and the wind - chill is - 15°f. what is the difference between the temperature and the wind - chill?
a. - 21°f
b. - 6°f
c. 9°f
d. 21°f

Explanation:

Step1: Identify the values

The temperature is - 9°F and the wind - chill is - 15°F.

Step2: Calculate the difference

We use the formula for the difference between two numbers \(a - b\), where \(a=-9\) and \(b = - 15\). The difference \(d=-9-(-15)\). According to the rule of subtracting a negative number (\(a-(-b)=a + b\)), we have \(d=-9 + 15\).
\(d = 6\)

Answer:

6°F
