Answer:

9 hours

Steps:

3x + 20 = 47

3x = 27

x = 9

Step-by-step explanation:

The starting temperature is 20°F, and it rises 3° every hour.

We know in x hours, the temperature will be 47°F.

So our equation is 3x + 20 = 47

Since the temperature is already 20°, we will subtract 20 from 47, leaving us with 27.

What number, multiplied by 3, is 27?

9.

Therefore, we know in 9 hours, the temperature will be 47°F.
