Question

One winter in North Dakota, the temperature dropped to −37° Fahrenheit. How many degrees must the temperature increase to reach 0° Fahrenheit?

Answer 1

Let "x" be the number of degrees needed for the temperature to be increased to reach 0°

So we now have,

`\begin{gathered} -37^0\text{ + x = 0} \\ x\text{ = 0 + 37} \\ x=37^0 \end{gathered}`

For the temperature to be increased to reach 0° Fahrenheit, 37° Fahrenheit is what is needed.
