Answer: Our required equation would be 
Step-by-step explanation:
Since we have given that
y=30, when x = 6.
As there is direct proportion between x and y.
so, it becomes,
So, the equation connecting y and x would be
When we put the value of k, we get that
Hence, our required equation would be y=5x
 
        
             
        
        
        
Answer:
n=32/5
Step-by-step explanation:
 
        
             
        
        
        
Answer:
20
Step-by-step explanation:
x / 100 = 0.2
Multiply both sides by 100 to isolate x. 100 x 0.2 = 20
 
        
                    
             
        
        
        
For every side you just add 90 to your equation. so #4 would be 360-125-125-55=(55)
