If 3 tickets to a certain show cost $13.20, what would 7 tickets cost?

What is this answer?

Answers

Answer 1

Answer:

$ 30.8

Step-by-step explanation:

ratio and proportion:

3 tickets  = 7 tickets

$13.20            x

then cross multiply:  3 (x) = 13.20 (7)

simplify: 3x = 92.4

solve for x = 92.4 / 3

x = $ 30.8

therefore,

7 tickets costs $ 30.8

Step-by-step explanation:

formula to find mindpoint is

[tex](\frac{x2 + x1}{2} \frac{y2 + y1}{2} )[/tex]

(4,2) = (x1, y1)

(10,10) = (x2,y2)

now substitute those into the formula!

[tex]\frac{10 + 4}{2} \frac{10 + 2}{2} [/tex]

now solve for x & y !!

[tex]x = \frac{10 + 4}{2} = \frac{14}{2} = 7[/tex]

[tex]y = \frac{10 + 2}{2} = \frac{12}{2} = 6[/tex]

so now that we have solved for x & y put it in point form and your done !!

point for is (x,y)

and thanks why the Midpoint is (7,6)

Regent Stadium charges $20 for a seat in the bleachers, $30 for an end zone seat, and $40 for the excellent seats near the 50-yard line. When the stadium is full, 500 tickets were sold for a total of $14,000. The number of bleacher seats is the same as the number of end zone and 50-yard line seats combined.

Answers

Answer:

The number of bleachers seat sold = 200

The number of end zone seats sold =200

The number of excellent seats sold =100

Step-by-step explanation:

Let there are bleachers seats =x

The number of zone seats =y

The number of excellent seats =z

So, we can set up equations for given sentences as

x+y+z= 500

20 x+30 y+40 z=14000

x=y

Substitute x as y into first two equations

y+y+z=500

20 y+30 y+40 z=14000

Simplify each

2 y+z=500

50 y+40 z= 14000

Multiply 2 y +z=500 by -40 to eliminate z terms when we add them.

-80 y-40 z=-20000

Add this with 50 y +40 z=14000, which gives

-30 y=-6000

Divide both sides by -30

y=200

Now, plug in y as 200 into any of the equations to find z.

2(200)+z=500

400+z =500

Subtract both sides 400.

z=100

Now, we know x=y

So, x=200

Answers

Answer:

y = - [tex]\frac{1}{3}[/tex] x + 5

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m= [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 6, 7) and (x₂, y₂ ) = (- 3, 6)

m = [tex]\frac{6-7}{-3+6}[/tex] = [tex]\frac{-1}{3}[/tex] = - [tex]\frac{1}{3}[/tex] , thus

y = - [tex]\frac{1}{3}[/tex] x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (- 3, 6 ), then

6 = 1 + c ⇒ c = 6 - 1 = 5

y = - [tex]\frac{1}{3}[/tex] x + 5 ← equation of line

Step-by-step explanation:

Since a is 6 and b is 24 we would have to multiply both of those numbers which would give you 144.

Hope this helps and good luck!!

When a = 6 and b = 24, the value of the equation ab will be 144.

What is Algebra?

Algebra is the study of mathematical symbols, while logic is the manipulation of those signifiers.

Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction is referred to as the PEMDAS rule. To answer the problem properly and accurately, this rule should be followed.

The expression is given below.

⇒ ab

If the values of "a" and "b" are 6 and 24, respectively. The expression's value is then provided as,

⇒ a × b

⇒ 6 × 24

⇒ 144

When a = 6 and b = 24, the value of the equation ab will be 144.
