5. 3x-X-7=3 6.3x-3-X=3 7. -1 - 2x +3x=5 8. 3x - 22 - X=6 9. 2x+3x-10=10

Marta_Voda [28]

** 3x - x -7 = 3

2x = 10

x = 5

** 6. 3x - 3 -x = 3

18x - 3 - x = 3

17x = 6

x = $\frac{6}{17}$

** 7. -1 - 2x + 3x = 5

-7 - 2x + 3x = 5

-7 + x = 5

x = 12

** 8. 3x - 22 - x = 6

24x - 22 - x = 6

23x = 28

x = $\frac{28}{23}$

** 9. 2x + 3x -10 = 10

18x + 3x - 10 = 10

21x = 20

x = $\frac{20}{21}$

A Poker club has 10 members. A president and a vice-president are to be selected. In how many ways can this be done if everyone

Nesterboy [21]

Answer:

90 different ways

Step-by-step explanation:

We have a total of 10 members, and we want to find how many groups of 2 members we can have, where the order of each member in the group of 2 is important, so we have a permutation problem.

To solve this problem, we need to calculate a permutation of 10 choose 2.

The formula for a permutation of n choose p is:

$P(n, p) = n! / (n - p)!$

So we have:

$P(10, 2) = 10! / (10 - 2)!$

$P(10, 2) = 10! / 8!$

$P(10, 2) = 10*9 = 90$

So there are 90 different ways of choosing a president and a vice-president.

Thways Period: 1) Describe the difference between simple and compound interest.

Pepsi [2]

Answer:

While both types of interest will grow your money over time, there is a big difference between the two. Specifically, simple interest is only paid on principal, while compound interest is paid on the principal plus all of the interest that has previously been earned.
