Answer:
4 trips 
Step-by-step explanation:
Given that:
Dimension of rectangular tank :
(20cm * 30cm * 40cm)
Dimension of cubic container used to fill tank = 20cm per side
Volume of tank = (20 * 30 * 40) = 24400 cm³
Volume of cubic container = (20 * 20 * 20) = 8000 cm³
Number of trips it would take :
Volume of tank / volume of container
24400 cm³ / 8000 cm³
= 3.05
Hence, it will take 4 trips 
 
        
             
        
        
        
Answer:
9
Step-by-step explanation:
 
        
                    
             
        
        
        
10y - 5x = 40   Add 5x to both sides
       10y = 5x + 40   Divide both sides by 10
          y = 

x + 4
The 
y-intercept is 4 and the 
slope of the line is 
.
You can find these by comparing your equation to the equation y = mx + b, where m is the slope of the line and b is the y-intercept.
