Answer: r = 7
Step-by-step explanation:
Subtract 12 from both sides to isolate the r variable. You have -42 = -6r. Divide both sides by -6 to get r by itself and you get r = 7. Verify by substituting 7 as the r value and solving the equation. 
 
        
                    
             
        
        
        
100%  = 24000 
50 %  =  12000
10%   =   2400
5 %    = 1200
1 %    = 240
        
             
        
        
        
Answer:
50 days 
Step-by-step explanation:
Step one:'
given data
 Non member must pay a 6$ per day
let number of days be x
cost = 6x
member of the club pay 1$ but must pay a yearly membership fee of 250
cost = 250+x
Step two
equate the two expression to find x
6x=250+x
6x-x= 250
5x=250
divide both sides by 5
x= 250/5
x=50 days 
 
        
             
        
        
        
Answer:
2-3x=-6
We simplify the equation to the form, which is simple to understand 
2-3x=-6
We move all terms containing x to the left and all other terms to the right. 
-3x=-6-2
We simplify left and right side of the equation. 
-3x=-8
We divide both sides of the equation by -3 to get x. 
x=2.66666666667
God bless you and have a beautiful rest of the day!
