Answer:
48
Step-by-step explanation:
Create an equation to represent this, where x is the unknown number.
 + 6 = 18
 + 6 = 18
Solve for x, by first subtracting 6 from both sides:
 = 12
 = 12
Multiply each side by 4:
x = 48
So, the number is 48
 
        
                    
             
        
        
        
The value of 4 in 40 is 10 times less than the value of 4 in 400
        
                    
             
        
        
        
Number of apples=12 times numer of bags=12n
neeeds at least 75 apples (1 per student)
12n≥75
divide both sides by 12
n≥6.25
can't buy 0.25 of a bag
7
needs to buy 7 bags
        
             
        
        
        
Answer: 9 and 7eights
Step-by-step explanation: Divide using long division. The whole number portion will be the number of times the denominator of the original fraction divides evenly into the numerator of the original fraction, and the fraction portion of the mixed number will be the remainder of the original fraction division over the denominator of the original fraction. Which would equal, 9 and 7eights.
