Well, you should probably check with somebody else but i had got 26.5 or 26 1/2. I'm not sure if that is correct due to it saying to use quadratic equations. Sorry
        
                    
             
        
        
        
Answer:
x= 200
Step-by-step explanation:
The given equation is:
1/5 x - 2/3 y = 30
The value of y is 15
Put the value of y in the given equation:
1/5 x - 2/3(15) = 30
1/5 x- 10 = 30
Take the L.C.M of the denominator
x-50/5 = 30
Move the denominator to the R.H.S
x-50 = 30*5
x-50 = 150
Combine the like terms
x= 150+50
x = 200
The value of x is 200...
 
        
                    
             
        
        
        
Answer:
1) 
23265
2) 
 9478.125
3) 102369.09375
Formula nonsense: V=l*w*h
1) meaning V= 33*47*15 so V= 23265
2) meaning V= 22.5*33.7*12.5 so V= 9478.125
3) meaning V= 122.25*50.75*16.5 so V= 102369.09375
