Answer:
The answer to your question is: x = 15 and y = 17
Step-by-step explanation:
∠A = 6x
∠B = 9y - 63
they are linear pair, their addition gives 180°
but it also mention that linear pair with equal measure, so each angle measures 90°
6x = 90
x = 90/6
x = 15
9y - 63 = 90
9y = 90 + 63
9y = 153
y = 153/9
y = 17
1 lap in 2.5 minutes
so 4 in 10 minutes and 12 in 30.
Also 0.4 laps in 1 minute
I think it might be 2 because 20 divided by 2 there is no left over
C is the answer you are looking for.

y 7 3 1 </span>
avgroc = ( 1 -7) / (5 - -1) = -6/6 = -1
