Question

Problem Solving with Integers The temperature increased \(4^{\circ} \mathrm{F}\) from \(-1^{\circ} \mathrm{F}\). What is the new temperature?

Short answer

Answer: The new temperature is 3°F.

Step-by-step solution

Write down the given values

We are given that the initial temperature is \(-1^{\circ}\mathrm{F}\) and it increased by \(4^{\circ} \mathrm{F}\).

Set up the equation

To find the new temperature, we need to add the initial temperature to the increase in temperature: $$\text{New Temperature} = \text{Initial Temperature} + \text{Increase in Temperature}$$

Substitute the given values into the equation

Now, we substitute the given values into the equation: $$\text{New Temperature} = -1^{\circ}\mathrm{F} + 4^{\circ} \mathrm{F}$$

Add the temperatures

Add the temperatures together: $$\text{New Temperature} = -1 + 4$$

Calculate the new temperature

Finally, calculate the new temperature: $$\text{New Temperature} = 3^{\circ}\mathrm{F}$$ So, the new temperature is \(3^{\circ}\mathrm{F}\).
