Question

Starting at 1:00 p.m., the temperature changes -4 degrees Fahrenheit per hour. Write and solve an equation to find how many hours x it will take to reach -1°F. The equation is -4x = -1. It will take x hours to reach -1°F.

Answer 1

It will take 0.25 hours, or 15 minutes, to reach -1°F.

Step-by-step explanation:

In order to find how many hours it will take to reach -1°F, we can use the equation -4x = -1.

To solve for x, we divide both sides of the equation by -4: x = -1 / -4.

This simplifies to x = 1/4 or 0.25 hours.

Therefore, it will take 0.25 hours, or
