3(4+n)=18+n
distribute
12+3n=18+n
minus n both sides
12+2n=18
minus 12 both sides
2n=6
divide by 2
n=3
the number is 3
equation is
3(4+n)=18+n
The answer is c as -2 is -2/1 , -2/1 times 1/2 equals -1 which makes it so If x is -2 or less than it won’t exceed -1
Using the combination formula, it is found that 2,220,075 committees can be formed.
The order in which the people are chosen is not important, hence, the <em>combination formula</em> is used to solve this question.
<h3>Combination formula:
</h3>
is the number of different combinations of x objects from a set of n elements, given by:
In this problem, 8 people are chosen from a set of 12 + 15 = 27, hence:

2,220,075 committees can be formed.
