Find the value of the combination. From a committee consisting of 8 men and 5 women, a subcommittee is formed consisting of 4 me
Alex787 [66]

Out of 8 men, 4 can be selected and lined up in (8 x 7 x 6 x 5) = 1,680 ways.
But within that number, each group of 4 appears in (4 x 3 x 2) = 24 orders.
So there are (1,680 / 24) = 70 different groups of men.

Out of 5 women, 3 can be selected and lined up in (5 x 4 x 3) = 60 ways.
But within that number, each group of 3 appears in (3 x 2) = 6 orders.
So there are (60 / 6) = 10 different groups of women.

Each different group of 70 men can be joined by any of the 10 groups
of women. So the total number of possible subcommittees is (70 x 10) = 700 .

Equation Practice with vertical angles <br><br><br>Please solve for x
Harrizon [31]

Answer:

x=20

Step-by-step explanation:

These angles are vertical angles so they are equal.

7x-99 = 2x+1

Subtract 2x from each side

7x-2x -99 = 2x-2x+1

5x -99 =1

Add 99 to each side

5x-99+99 = 1+99

5x = 100

Divide each side by 5

5x/5 =100/5

x = 20
