Answer: 20ways
Step-by-step explanation:
Number of candies = 7
Number of kids = 4
Since each kid must receive at least one candy ;
Therefore number of candies left to ration is
7 - 4 = 3 candies ; among 4 kids.
To share 'n' identical object among 'r' number of individuals can be expressed in the form :
[n+(r-1)Cr-1]
n = 3 ; r = 4
[3+(4-1)C4-1] = 6C3
Recall: nCr = n! / (n-r)!r!
6C3 = 6!/(6-3)!3!
6C3 = 6!/3!3!
= (6 * 5 * 4) / (3 * 2 * 1)
= 120 / 6
= 20ways
Answer:
Step-by-step explanation:
- 20 + 2 < x/3 - 8
- 22 + 8 < x /3
- 30 < x /3
- 30*3 < x
- 90 < x
- x > 90
Correct choice is C
For six you can write 1/4 because there is 4 pennies and 1 represents each penny
for number 5 you can put 2/10 because there is 10 coins and 2 quarters
and for number 7 is that Bradley has 10 coins not 9 so it would be 1/10
Subtract the sides of the equation minus 3
Divided the sides of the equation by 2
So ;
