Answer:

The price of one Balcony seat = $50

The price of one Ground level seat = $90

The price of one VIP seat = $180

Step-by-step explanation:

Let the price of one Balcony seat = $x

Let the price of one Ground level seat = $y

Let the price of one VIP seat = $z

As per the given table:

135x+280y+29z=37170 ....... (1)\\150x+270y+58z=42240 ....... (2)\\130x+265y+29z=35570 ....... (3)

Multiplying (1) with 2 and subtracting (2) from it:

120x+290y=32100 \\12x+29y=3210..... (4)

Subtracting (3) from (1):

5x+15y=1600\\x+3y=320 ....... (5)

Multiply equation (5) with 12 and subtracting (4) from it:

7y=630\\\Rightarrow y =\bold{90}

By equation (5), putting value of y:

x=\bold{50}

By equation (1), putting the values of x, y:

135\times 50+280\times 90+29z=37170\\\Rightarrow 29z=37170-31950\\\Rightarrow 29z=5220\\\Rightarrow z =\bold{180}

Therefore, the answers are:

The price of one Balcony seat = $50

The price of one Ground level seat = $90

The price of one VIP seat = $180

The sides

12-3a

12-3a

4(2a-5)=8a-40

so for perimeter we + them

(12-3a)+(12-3a)+(8a-40)

=

2a-16

Find the perimeter of quadrilateral ABCD with vertices A(-2,-2), B(-1,3),
drek231 [11]

Answer:

<h2> 22.2</h2>

Step-by-step explanation:

Step one

given the coordinates

ABCD with vertices A(-2,-2), B(-1,3), C(5, 3), and D(4, -2)

AB=(-2,-2),(-1,3)

BC=(-1,3), (5, 3)

CD=(5, 3),(4, -2)

DA=(4, -2),(-2,-2)

The distance between points AB=

AB= \sqrt (x_2-x_1)^2+(y_2-y_1)^2

AB= \sqrt (-1+2)^2+(3+2)^2\\\\AB= \sqrt 1^2+(5)^2\\\\AB= \sqrt26\\\\AB=5.1

The distance between points BC=

BC= \sqrt (5+1)^2+(3-3)^2\\\\BC= \sqrt 6^2+(0)^2\\\\BC= \sqrt36\\\\BC=6

The distance between points CD

CD= \sqrt (4-5)^2+(-2-3)^2\\\\CD= \sqrt -1^2+(-5)^2\\\\CD= \sqrt26\\\\CD=5.1

The distance between points DA

DA= \sqrt (4+2)^2+(-2+2)^2\\\\DA= \sqrt 6^2+(0)^2\\\\DA= \sqrt36\\\\DA=6

Hence the perimeter = 5.1+6+5.1+6

= 22.2

Use the diagram to find the angle measures of the triangle. Recall that the sum of the angle measures of a triangle is 180 degre
My name is Ann [436]

Answer:

x =29

x+6 =35

4x = 116

Step-by-step explanation:

The sum of the angles of a triangle is 180

x+ (4x) + (x+6) = 180

Combine like terms

6x+6 = 180

Subtract 6 from each side

6x+6-6 = 180-8

6x = 174

Divide each side by 6

6x/6 = 174/6

x =29

x+6 = 29+6 = 35

4x = 29*4 =116
