17% because you would do the number of times it landed on section a (14) over the total times spun (84) which gives you 16.6666 (16 2/3) which would round up to 17%. Hope this helps!
Since we are finding the inverse you switch the variable. So it is now x=7y+2 and now you solve for y. You would get x-2/7 = y for the inverse
Answer: 3

Answer:
y=21 X=39
Step-by-step explanation:
expand brackets on first equation: 2x+2y=120
now divide the second equation by 2 on both sides:
2x+y/3=85
then subtract the second equation from the first equation
so (2x+2y) - (2x+y/3)
the 2x on both sides cancel out and you get 5/3 y
this is equal to the sum of the first equation subtract the second equation which is 35
divide both sides by 5/3 and you get
y=21
substitute y in the first equation and you get X=39
