SVETLANKA909090 [29]

Answer:

66

Step-by-step explanation:

If there are  <em>n</em>  students, then the number of pairs is \frac{n(n-1)}{2}.

With 12 students, \frac{12(12-1)}{2} = \frac{132}{2}=66 pairs can be formed.

The reason the formula works is this:  Each of the 12 students can be paired with 11 other students (no student is paired with him/her self).  But counting 12 x 11 = 132  counts each pair <u>twice</u>.  Example: student A can be paired with student B,..., student B can be paired with student A.  The pair was counted two times.

See the attached image that shows pairings of 5 students.  There are

5(5 - 1)/2 = 5(4)/2 = 10 pairs.

2q+4q+3 what do it equal
Leto [7]

Add the similar variables (think apple+apple), in this case, we would add 2q+4q.

Well, what is 4 apples plus 2 apples? 6 apples, simply, 6q

Since 3 is without a variable, we will leave it as is

Therefore, 2q+4q+3= 6q+3

Hope this helped :)
