15.
boyakko [2]

Explanation:

a)

{3 \choose 2} = \frac{3!}{2!(3-2)!} = \frac{6}{2*1} = 3

{3 \choose 1} = \frac{3!}{1!(3-1)!} = \frac{6}{1*2} = 3

b) First, we have that

{n \choose k} = \frac{n!}{k!(n-k)!}

On the other hand,

{n \choose n-k} = \frac{n!}{(n-k)!(n(n-k))!} = \frac{n!}{(n-k)!k!}

Therefore, both expressions are equal. This makes sense, because selecting k elements from a group of n is the same than specify which elements you will not select. In order to specify those elements you need to select the n-k elements that will not be selected. Hence, each time you are selecting k from n, you are also selecting n-k from n, and from that reason both combinatorial numbers are equal.

How do you solve this equation 1/3(x+1)+2x=2.
SashulF [63]

Answer: x = 5/7

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

1/3 (x + 1) + 2x = 2

(1/3) (x) + (1/3) (1) + 2x = 2 (Distribute)

1/3x  + 1/3 + 2x = 2

(1/3x + 2x) + (1/3) = 2 (Combine Like Terms)

7/3x + 1/3 = 2

Step 2: Subtract 1/3 from both sides.

7/3x + 1/3 - 1/3 = 2 - 1/3

7/3x =  5/3

Step 3: Multiply both sides by 3/7.

(3/7) * (7/3x) = (3/7) * (5/3)

Answer: x = 5/7
