Answer:
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 :)
