Jake and Gloria are running on the track team. Gloria can run twice as many miles as

Jake. Write an equation that can be used to determine how far Jake runs if they run a combined distance of 12 milles.

J+2J=12 so 3J=12 so J=4

Step-by-step explanation:

Use J to represent Jake's miles.

We know that Gloria's miles (G) is twice J, so G=2J

We also know that Jake and Gloria together ran 12 miles.

So we know, J+2J=12 or 3J=12 meaning J=4

So Jake runs 4 miles, and since Gloria is two times that she ran 8 miles.
