Answer:

r = 90

Step-by-step explanation:

Our goal is always to get the variable we're trying to solve for on one side of the =, and everything else on the other side. Since we are solving for r here, we want to get rid of the 20 first, and then the 2.

subtract 20 from both sides:

  • 2r = 200 - 20 = 180

divide both sides by 2:

  • r = 180 / 2 = 90

Steps for solving:

Start by isolating 2r by subtracting 20 from both sides.

This leaves us with 2r = 180.

Now divide both sides by 2 and <em>r = 90</em>.

The temperature in frostville was at 50*F at midnight,and it dropped at a constant rate for the next 10 hours.
bazaltina [42]

After 10 hours the temperature is shown on the graph as 30 degrees.

50 degrees - 30 degrees = 20 degrees.

The temperature dropped 20 degrees in 10 hours.

Divide the change by the time:

20 degrees / 10 hours = 2 degrees per hour.

Because the temperature dropped, the change would be negative.

The answer is D. -2 degrees per hour.
