Gnom [1K]

102 adult tickets were sold.

Step-by-step explanation:

Let,

Adult tickets = x

Children tickets = y

According to given statement;

x+y=146 Eqn 1

8x+5y=1036 Eqn 2

$Multiplying\ Eqn\ 1\ by\ 5\\5(x+y=146)\\5x+5y=730\ Eqn\ 3\\Subtracting\ Eqn\ 3\ from\ Eqn\ 2\\(8x+5y)-(5x-5y)=1036-730\\8x+5y-5x-5y=306\\3x=306\\Dividing\ both\ sides\ by\ 3\\\frac{3x}{3}=\frac{306}{3}\\x=102\\$

Clara created a coordinate grid of her city. The bowling alley is located at (10, 12) and the skating rink is located at (-6, -4

yulyashka [42]

First we need to know the coordinates of the movie theater, we can do this applying the midpoint formula:

$\begin{gathered} P(BA,SR)=(\frac{10-6}{2},\frac{12-4}{2})\text{ = (}\frac{4}{2},\frac{8}{2}) \\ \Rightarrow P(BA,SR)=(2,4) \end{gathered}$

We have that the movie theater is located at (2,4). Now we use this coordinates to find the location of Clara's house using again the midpoint formula:
