Answer:
1. m=1/2
2. x=4/7
3. t=4
4. y=5
Step-by-step explanation:
1. 5m+4=7m+6
 5m-7m=6-5
 2m=1
 m=1/2
2. -5x+3=2x-1
 -5x-2x=-1-3
 -7x=-4
 x= -4/-7= 4/7
3. 5t-3=3t+5
 5t-3t=5+3
 2t=8
 t=8/2= 4
4. 53y-55= 42y
 53y-42y=55
 11y=55
 y=55/11=5
hope it helps!

Answer:
The value is      
Step-by-step explanation:
From the question we are told that 
    The amount charge per year is  
    The  number of members it will have at this amount is  
    The amount amount increase that will lead to the loss of a single member is   
         Generally the total amount the club would obtain from  its members is mathematically represented as 
       
Now let x denote the number of member lost 
Hence 
       
=>    
=>  
Thus the number of members that be removed to  give the maximum  income from dues is obtained by differentiating the above equation and equating it to zero
            
=>         
So from   we have
 we have 
           
            
So the amount the club should charge is
