The percentage of walkers who got a ride is 37.5/3=12.5%
The number of that is 0.125*24=3 students.
The probability of you picking 7 is 1/4 because there are 4 cards, and the probability of getting a card greater than 7 would be 2/3 (if you already picked 7) if not it would be 2/4, but I’m assuming it mean that you picked seven and now you’re trying to pick a higher card so i would go with 2/3
The value that makes the equation true is 3!
7(3) + 1 = 22
.75x-14=-8
Use inverse operations to find x
Add 14 on both sides
.75x=6
divide by .75 on both sides
x=8
