Permutations vs combinations(one step):

Bogdan [553]

Answer:

the expression is: $^{15}P_3=\frac{15!}{(15-3)!}$

and 2730 different ways are possible.

Step-by-step explanation:

In the given question we have to choose a president, vice

president, and secretary.

Permutations are used when order is important so, as in the given question order is required. We would use permutations

The formula used is: $^nP_r=\frac{n!}{(n-r)!}$ where:

n=total number of objects

r=number of objects selected

In our case: n=15, r=3

Putting values and finding the answer:

$^nP_r\\^{15}P_3=\frac{15!}{(15-3)!} =2730 \ ways$

So, the expression is: $^{15}P_3=\frac{15!}{(15-3)!}$

and 2730 different ways are possible.

6/x-8=2/x+6 how do i solve this

lutik1710 [3]

6/(x-8)=2/(x+6)
times both sides by (x-8)(x+6)
6(x+6)=2(x-8)
distribute
6x+36=2x-16
minus 2x both sides
4x+36=-16
miinus 36 both sides
4x=-52
divide both sides by 4
x=-13
