Answer:
C
Step-by-step explanation:
This is a combination question.
In the first instance, we select 5 from 20 and in the second case , we select 4 from 20.
The total number of ways to solve the first instance is 20C5 = 15504 ways
The total number of ways to solve the second instance is 20C4 = 4,845
The ratio of the first to the second scenario is 15,504/4,845 = 3.2 = 16 to 5

Answer:
So first, they remove the denominator of x times x, because multiplication cancels out division, so then you're left with
3/1 times x = 2193
3/1 just equals three, so you write it down as 3.
3x = 2193
To isolate 3x, you need to divide by 3.
x = 731
Hope this helped :)
Are you sure? i got y=-x/6+4/3 or y=-x/6+1.33333.....
