Skylar went 13ft per second
Rodrigo went 13 1/2 ft per second
So, 1/2 a ft per second
+8y and -8y cross out.
So the first one is 3x=15
Second one is 2x=10
x=5
Then plug x is one of the equations
2(5)-8y=10
10-8y=10
x=5
y=0
In y=x-4 your slope is 4.
In 2x+4=5 = 0.5
Option D should be your answer.
No combo of any of those angles add up to exactly 180 to suggest that they are parallel lines.
(93+75+86+x)/4=81
93+75+86+x=324
The sum of the scores is 324. Now solve for x:
254+x=324
x=70
The answer is 70
