The community college fine arts department sold three kinds of tickets to its latest dance presentation. The adult tickets sold
lana [24]

Answer:adult=75

Students = 200

Children=75

Step-by-step explanation:

Let x= adult tickets, y=students, z=child

x+y+z =350

Since x=z

y+2z= 350 -----------1

20x +12y + 10z = 4650

Since y=z

12y +30z = 4650 --------2

Using elimination method to solve eqn 1&2

Multiply eqn 1 by 12

12y + 24z = 4200

12y +30z = 4650

Subtract equ 2 from 1

-6z =-450

z=75, x = 75

y=350 -(75+75)

y= 200 tickets

A line segment has endpoints at (1,6) and (9,-10). The midpoint of the segment is located​
ira [324]

Answer:

The answer is

<h2>( 5 , - 2 )</h2>

Step-by-step explanation:

The midpoint M of two endpoints of a line segment can be found by using the formula

M = (  \frac{x_1 + x_2}{2} , \:  \frac{y_1 + y_2}{2} ) \\

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(1,6) and (9,-10)

The midpoint is

M = ( \frac{1 + 9}{2}  \:  , \:  \frac{6 - 10}{2} ) \\  = ( \frac{10}{2}  \: , \:  -  \frac{4}{2} )

We have the final answer as

<h3>( 5 , - 2)</h3>

Hope this helps you

The container that holds the water for the football team is 23 full. After pouring out 2 gallons of water, it is 12 full. How ma
Mama L [17]
Let full be f and gallons be g
23f-2g=12f
2g=23f-12f
2g=11f
g=5.5f
note 23f is when it is full and x is the number of gallons the container can hold.
g=5.5f
xg=23f
x=46÷11
∴x approximately is 4.9
