Answer:

C is correct. 
Step-by-step explanation:
At a picnic, 
Number of adults is 3 times as number of children. 
Number of women is twice as number of men. 
Total number of men, women and children at the picnic be x
Let number of children be c
Let number of men be m 
Let number of women be w
# Number of women is twice as number of men, w = 2m 
# Number of adults is 3 times as number of children, w + m = 3c
       2m + m = 3c     (∴  w=2m )
                 c = m
Total number of men, women and children at the picnic be x
∵       c + m + w = x
      m + m + 2m = x
                     4m = x
Number of men, 
Hence, The total number of men will be  
 
        
             
        
        
        
Answer:[m, m+d, m+2d, - - - - -, n] 
Step-by-step explanation:
We know the formula for arithmetic progression is a_(n) = a_(1) + (n-1)d
Where a_(n) is the nth term of the sequence 
a_(1) is the first term of the sequence 
n is the number of the term like if we are talking about 7th term so the n is 7.
d is the difference between two successive terms. 
For this problem we know our first term that is m, our last term that is n and our difference that is d. 
For second term we will use the formula
a_(2) = m + (2-1)d
a_(2) = m + (1)d
a_(2) = m + d
Similarly, 
a_(3) = m + (3-1)d
a_(3) = m + (2)d
a_(3) = m + 2d

Answer:
78 laundries
$0.25
Step-by-step explanation:
If the box contains 195 scoops and at once he uses 2 1/2 you have to divide 195 by 2 1/2 and you get 78.
How much is he paying for each load? you have to find the unit rate. The box costs $19.99 he can do 78 laundries at once so you divide the money by the quantity or in other words $19.99 by 78 and get 0.2562820512820513, since we are talking about money we use only the firs two decimals, so he pays $0.25 per load of laundry.
