Eight students got a B on the final test. If the ratio of the number of studenst who got an A to the number of student who got a B is y : X, how many students got an A? What if x is 2 and y is 3?

1) x = 2 and y = 3: 12 students got an A.

2) x = 4 and y = 3 6 students got an A. (from the comments)

Step-by-step explanation:

Hopefully I read this right, but the ratio you're trying to find is A : B = y : x

1) Plug in x = 2 and y = 3 to get 3 : 2. Because we know 8 students got a B we're going to multiply by 4 on each side to get 12 : 8 (12 A students and 8 B students).

2) You asked this in the comments so I answered it as well. Do the same thing as 1):

Plug in x = 4 and y = 3 to get 3 : 4.

We know there's 8 B students so multiply by 2 to get 6 : 9. 6 A students and 9 B students.

x=2 and y=3 12 students got an A.

x=4 and y=3 6 students got an A.

Step-by-step explanation:

hope this helps sry its really late and sry if its wrong i tried :|

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
