Adult tickets to a play cost $22.00 Tickets for children cost $15.00. Tickets for a group of 11 people cost a total of $228.00.

Write and solve a system of equations to find how many children and how many adults were in the group.
Here is the set up:

Let x represent the number of adults
Let y represent the number of children

x + y = 11 (only 11 people were in the group )
22x + 15y = 228 ( This is the equation that deals with money )

Now you finish it.

Answer:

The answer to your question is 9 adults and 2 children

Step-by-step explanation:

Data

adult ticket = $22

children ticket = $15

Total people= 11

total cost = $228

Number of adults = x = ?

Number of children = y = ?

Process

1.- Write equation to solve the problem

              x + y = 11                           Equation l

           22x + 15y = 228                  Equation ll

-Solve Equation l by x

              x = 11 - y                            Equation lll

-Substitute equation lll in equation ll

          22(11 - y) + 15y = 228

-Solve for y

         242 - 22y + 15y = 228

-Simplify like terms

                -7y = 228 - 242

                -7y = -14

                   y = -14/-7

                  y = 2

-Find x

              x = 11 - 2

              x = 9

2.- Conclusion

There were 9 adults and 2 children.

Provide an example of how a free press is an essential component of a democracy
Pepsi [2]

Answer:

Free press is essential since the government does not control the press.

Step-by-step explanation:

For example, the Untied States has free press so authors can spread information (whether for good or evil) while other countries like China control their press and access to press outside of their country, making it much harder for citizens to see the world from another perspective rather than what the government is willing to tell them.

Since the United States is a democracy, it is important to allow their citizens to have the right to speech and the press if people want to form opinions of their own.

The graph shows the location of point P and point R. Point R is on the y-axis and has the same y-coordinate as point P. Point Q
Mumz [18]

Answer:

n = 5

Step-by-step explanation:

Coordinate of P = (n,3)

R is on y-axis & the y-coordinate of P & R are equal. So coordinate of R = (3,0)

Coordinate of Q = (n,-2)

Using distance formula,

Distance between P & Q =

\sqrt{ {( n  -  n}) ^{2} +  {( 3-  ( - 2)  })^{2}   }

=  >  \sqrt{ {(3 + 2)}^{2} }  =  \sqrt{ {5}^{2} }  = 5

Distance between P & R =

\sqrt{ {(n - 0)}^{2} +  {(3 - 3)}^{2}  }

=  >  \sqrt{ {n}^{2} }  = n

But in question it is given that distance between P & Q is equal to the distance between P & R. So,

n = 5
