divide 40 by 5 for pages printed in 1 minute then multiply this by 8
 × 8 = 8 × 8 = 64 pages
 × 8 = 8 × 8 = 64 pages
 
        
                    
             
        
        
        
Answer:
33
Step-by-step explanation:
Assume that each cell on the grid represents one unit. One can use the formula, ( ) to find the area of the triangle. One can see that the base of the triangle is, (11), and the height is (6). Substitute in the given values and solve for the area,

Answer:
 The value of x is 8 gallon.
Step-by-step explanation:
 Given a table  showing approximate conversion from gallons to liters.
Number of Gallons    2      4      x
Number of Liters      7.6  15.2  30.4
We are required to find value of x,
Given : 2 gallon is equal to 7.6 liters.
⇒  1 liter is equal to  liters. ........(1)
 liters. ........(1)
given, x gallon equal to 30.4 liters.
⇒ 1 liter is equal to  liters.  .........(2)
 liters.  .........(2)
from (1) and (2),
⇒  
Solving for x, we get,
⇒  
⇒  
Approximately x = 8 
Thus, the value of x is 8 gallon.
