The temperature is 8ºF. It is expected to rise 5ºF each hour for the next several hours. Write an equation to determine how many hours the temperature will rise until it is 48ºF outside.

8 + 5x = 48

Step-by-step explanation:

To construct this equation, we can begin with the values we need to have. The total temperature must equal 48°, so we can put this alone on one side of the equals sign.

The beginning temperature is 8°, so we will start the other side of the equation with this.

Next, the temperature will rise 5° every hour for an unknown amount of hours. To put this into equation form, the unknown, x, will be multiplied by 5. Or we can say this is 5x.

We can build our equation. Start with the 8 we began with. Add to this our 5x, the rate per hour. The total of this will equal 48.

So, the equation is-

8 + 5x = 48

Good luck ^^
