Total marbles = 13
Number of yellow = 2
probability of getting yellow = 2/13
Solve n by simplifying both sides of the equation, then isolating the variable.
n=7

According to the statement of the question, we have:
<h2>3X + 4 = 28</h2>
isolating X we get
X = 8
5:2 and 14:8 are not proportional, 3 to 4 and 24 to 18 are also not proportional, 5:6 and 2:8 are also not proportional, and 7 to 4 and 17.5 to 10 are also not proportional. 7 inches in 9 hours and 42 inches in 54 hours is proportional. 12 players from 21 teams and 15 players from 24 teams are NOT proportional.
