Answer:
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.
In order to simplify, let's add 6x and 13x.
We will get 19x, and that is the answer!
You take 67.8/100×15
10.17
then take 15-10.17 the answer will be the wrongs u got
=4.83
