(3x + 1/2 ) + ( 7x - 4 1/2 ) 
3x+7x + 1/2 - 4 1/2
10x -4
 
        
             
        
        
        
30% of 40 = 0.30(40) = 12......so 12 tables seat 4 people per table = 12 x 4 = 48 seats.......tables remaining seat 22 people (22 seats).
48 + 22 = 70 seats total
        
                    
             
        
        
        
Answer:
Maya is NOT correct  as 
 is  1/100 of the value 
Step-by-step explanation:
The value of 6 in 0.006 = 
Also, the value of 6 in 0.6  = 
But, 
 is not 1/10  of the value  
as 1/10  of the value  
  =  
Hence,Maya is NOT correct. 
 is  1/100 of the value 
 
        
             
        
        
        
The mode is what number occurs most often. So in this set, the number that occurs most often is 5. 
Mode = 5
The mean is the average of all the numbers in the set. To find the average of numbers, you add them all up then divide by how many numbers there are in the set. 5 + 6 + 8 + 3 + 5 + 7 + 4 + 11 + 5 + 7 = 61. 61 divided by 10 = 6.1 The answer is 6.1
Mean = 6.1
Good luck, my guy!
 
        
                    
             
        
        
        
If the digits are a, b and c, the number n is 100a+10b+c
Here are the equations:
a number equals fifteen times the sum of its digits: 
100a+10b+c = 15(a+b+c)
if its digits are reversed, the resulting number exceeds n by 396: 
100a+10b+c+396 = 100c+10b+a
the one’s digit is one larger than the sum of the other two: 
a+b+1 = c
Solving it gives you a=1, b=3, c=5, the number is 135.
