Answer:
D. 8x=16
Step-by-step explanation:
If y=2x, then
2x+3y=16
2x+3(2x) =16
2x +6x=16
8x=16
5.8
or
5.830952
Using distance formula
y=3
-5-7y=-20y+34 you add the 5 over and add 20y to the other side to get this:
13y=39 then you divide that by 13 to get the anser of 3.
i think that that the answer is 13 Step-by-step explanation:
