Solve for the value of x and y when 3x+2y=24 , x+y=9<br> step wise explanation plz
OLga [1]

Answer:

{x,y} = {2,9}

Step-by-step explanation:

Solve equation [2] for the variable  y  

 

 [2]    2y = -6x + 30

 [2]    y = -3x + 15

// Plug this in for variable  y  in equation [1]

  [1]    3x + 2•(-3x+15) = 24

  [1]    -3x = -6

// Solve equation [1] for the variable  x  

  [1]    3x = 6  

  [1]    x = 2  

// By now we know this much :

   x = 2

   y = -3x+15

// Use the  x  value to solve for  y  

   y = -3(2)+15 = 9

Seven people are in an elevator which stops at ten floors. In how many ways can they get off the elevator?
zlopas [31]

The number of ways people can get off the elevator is 604800 ways.

In this question,

Number of people, n = 7

Number of floors, r = 10

The first person can leave elevator in one of 10 ways. Then second person has to choose from one of remaining 9 floors. Then third person in 8, fourth in 7 ways and so on.

Number of ways people can get off the elevator can be calculated as

⇒ nP_r=\frac{n!}{(n-r)!}

⇒ 10P_{7}=\frac{10!}{(10-7)!}

⇒ 10P_{7}=\frac{10!}{(3)!}

⇒ 10P_{7}=\frac{(10)(9)(8)(7)(6)(5)(4)3!}{(3)!}

⇒ 10P_{7}=(10)(9)(8)(7)(6)(5)(4)

⇒ 604800 ways.

Hence we can conclude that the number of ways people can get off the elevator is 604800 ways.
