Answer:
56
Step-by-step explanation:
Recall that 1 lb = 16 oz, meaning that 1/2 lb = 8 oz.
Thus, we need only divide 28 lb by 1/2 lb to determine the number of 8 oz servings are contained in a 28 lb bag of dog food:
 28 lb
--------------------- = 56 8-oz servings
 1/2 lb/ serving

Answer: 864 tiles
Step-by-step explanation:
Rather than calculating the whole area of bathroom and area of one tile, It is quicker and easier to determine how many rows of tiles that will be needed. 
Note that 1 feet = 12 inches
Each tile measures 3 inches on each side.
Length: 9 feet = 9 × 12 = 108 inches
Therefore, 108/3 = 36 tiles will fit along the length.
Width: 6 feet = 6 × 12 = 72 inches. Therefore, 72/3 = 24 tiles will fit along the width. 
So, (36 × 24) = 864 tiles will be needed. 
 
        
             
        
        
        
Answer:
Equation shown 
Step-by-step explanation:
Eq(1): x-3y=-12
 X=-12+3y
 =-4+y
Eq(2): x-3y=-6
 X=-6+3y
 =-2+y
 
        
                    
             
        
        
        
Answer:
w=9
Step-by-step explanation:
Our equation is: 8w-15=57
Add 15 to both sides
-15 is now gone because we added 15 so it would be zero
and we have 72 because 15 plus 57 is 72
Now we have:
8w=72
Divide by 8 on both sides
8w cancels out to just w
and 72 divided by 8 is 9
And you're left with:
w=9
