Step-by-step explanation:
Since they are supplementary, it means the addition of both angles gives 180 degree.

It would be .43, rounded. You get this answer by taking all of the 10th graders (14) and looking at how many prefer sporting events (6). Then, you simply form a decimal from 6/14, and that comes out to .428, and .43 rounded up. I hope this helps! :)
Positive 20 and negative 10 is a net amount of 10. 10 minutes is 1/6 of an hour. 5*1/6=5/6km
For the first one the answer is y=-1x+6 which means x=-1 and y=6
