Question

The number line shows the change in temperature from 7:00 a.M. To 1:00 p.M. Which expression shows how to find the difference between the temperatures at 7:00 a.M. And 1:00 p.M.?

Answer 1

B

Explanation:

The options in the question and the number line are shown in the image attached.

From the options, it is clear that the difference between the temperatures at 7:00 a.M. and 1:00 p.M is;

Temperature at 7:00 a.M - Temperature at 1:00 p.M

We can see from the number line that the temperature at 7:00 a.M = -4

Temperature at 1:00 p.M = 16

difference between the two temperatures = ∣(-4) - 16∣ = 20
