Well,
we know that we need to accumulate points from x and y to reach 20 points.
since x provide 3 and y provide 4 points, the formula would be :
3x + 4y = 20 
or it can be written as : 
y = (3x/4)+5
hope this helps
        
                    
             
        
        
        
Answer:
12 servings!
Step-by-step explanation:
1/4 equals 0.25 gallons, 1/2 gallons is 0.5, so Will will have a mix of 0.75 gallons. If each serving is 1/16 and 1/16 equals 0.0625, divide 0.75 by 0.0625 = 12 servings.
 
        
             
        
        
        
Answer:
y= -2x + (-6)
or
y= -2x - 6
both work !
Step-by-step explanation:
 
        
             
        
        
        
Y = 172.972972972...
You need to isolate the variable, y. To do this, you need to divide both sides of the equation by 0.74. This gives you your final answer.
