F(x) = x2. What is g(x)?

3.25 miles

Step-by-step explanation:

Let's use x as a placeholder for the number you don't know yet.

2.3+x=5.55

To get the x by itself, we need to subtract 2.3. Remember, whatever we do to one side we have to do to the other side.

x=5.55-2.3

Now we must subtract 2.3 from 5.55.

5.55-2.3=3.25

Now we know:

x=3.25

Since the question asks for the answer in miles, we can say that Trevor ran 3.25 miles on Tuesday.

HTH :)
