Question

To get from home to work every day, Samos drives 7 miles east on Avenue A, and then drives north on Avenue B. He knows that the straight-lines distance from his hometo his place of work is about 25 miles. How many miles does he drive north on Avenue B?

Answer 1

The answer is 18 miles.

Explanation:

x is always a good strategy to find missing numbers, so let's use x.

Equation:

`7+x=25`

`25-7=18`

`7+18-7=18`

`25-7=18`

Answer 2

18 miles

Explanation:

7 + x = 25

-7 -7

x = 18
