Answer:
15 classes
Step-by-step explanation:
Let
x -----> the number of class
y ----> the total amount in charges
we know that
The total charge is equal to the number of class multiplied by the additional fee plus the membership fee (only members)
so
<em>Members</em>
 -----> equation A
 -----> equation A
<em>Non Members</em>
 -----> equation B
 -----> equation B
Equate equation A and equation B
 
 
Solve for x
 
 
 
 

 
        
             
        
        
        
Step-by-step explanation:
100.81834696...is your answer
or 100.81
 
        
             
        
        
        
Since the common number of the fraction 20/35 is 5 then divide both sides by 5 which would equal to 4/6 as the equivalent fraction
        
                    
             
        
        
        
Answer:
 x =-9 y=2
Step-by-step explanation:
-4+2y=0
2y=4. 
y=4/2
y=2
again
x+2y = -5
x+ 2* 2 = -5
x= -5 -4
x = -9
