9 +3 = 12 students
9 are male
1st = 9/12 = 3/4
2nd = 8/11
3/4 * 8/11 = 6/11
Answer = D) 6/11
Answer:
= 4
Step-by-step explanation:
first lets find the value of x in 3x+2=5/9
3x+2=5/9
3x =
-2
3x = 
3x = 
x = 
x = 
can also be written as 
−3x+8
-3 (
) +8
+8
= 4
<h3>Substitute and Check:</h3>

<h3>We can stop here and conclude that ( 1 , 3 ) is not a solution to this system, since it does not even satisfy the first equation, but check for the other one just in case:</h3>

Tan inverse 3/5 is 30.96
so the answer is x = 31.0
