The school that Joe goes to is selling tickets to a choral performance. On血e first day of ticket
ArbitrLikvidat [17]

Answer:

The price of one senior citizen ticket is $8, and the price of one child ticket is $11.

Step-by-step explanation:

You are looking for two things: the price of a senior citizen ticket and the price of a child ticket.

We need to write two equations using two variables.

Let s = price of 1 senior citizen ticket.

Let c = price of 1 child ticket.

First day of ticket sales:

6 senior citizen tickets, 8 child tickets, total sales of $136

Since s is the price of a senior citizen ticket, 6 tickets cost 6s.

Since c is the price of a child ticket, 8 tickets cost 8c.

The total sales is 6s + 8c.

The total sales is $136, so our first equation is

6s + 8c = 136

Now we do the same for the second day of ticket sales.

6 senior citizen tickets, 9 child tickets, total sales of $147.

Since s is the price of a senior citizen ticket, 6 tickets cost 6s.

Since c is the price of a child ticket, 9 tickets cost 9c.

The total sales is 6s + 9c.

The total sales is $147, so our second equation is

6s + 9c = 147

The system of equations is

6s + 8c = 136

6s + 9c = 147

Multiply both sides of the first equation by -1. Write the second equation below it. Then add the equations.

       -6s - 8c = -136

(+)     6s + 9c = 147

----------------------------

                  c =   11

c = 11, so the cost of a child ticket is $11.

Now substitute 11 for c in the first equation, and solve for s.

6s + 8c = 136

6s + 8(11) = 136

6s + 88 = 136

6s = 48

s = 8

The price of a senior citizen ticket is $8.

The price of a senior citizen ticket is $8, and the price of a child ticket is $11.

Which graph best represent the inequality? pictures down below , Thank you all <3
kow [346]

Answer:

y ≤ 3x+1

Step-by-step explanation:

when the line is solid with no spaces in between, that automatically rules out A) and C). and the shading is underneath the line so that rules out B) as well. Also, if you look through the line that passes through the Y-axis, you can see that it is on +1 so that automatically tells you that both -1 are out.

Hope this helped you!

A parking lot in the shape of a trapezoid has an area of 12,0521 square meters the length of the other base is 108.6 meters. Wha
andreev551 [17]

Please consider the complete question.

A parking lot in the shape of a trapezoid has an area of 12,052.1 square meters. The length of one base is 82.4 meters and the length of the base is 108.6 meters. What is the width of the parking lot

We will use area of trapezoid to formula to solve our given problem.

\text{Area of trapezoid}=\frac{1}{2}(a+b)\times h, where

a and b represents parallel sides of trapezoid,

h = height of trapezoid.

Width of the trapezoid will be equal to height.

Upon substituting our given values in above formula, we will get:

12,052.1=\frac{1}{2}(82.4+108.6)\times h

12,052.1\cdot 2=2\cdot \frac{1}{2}(82.4+108.6)\times h

24104.2=(191)\times h

\frac{24104.2}{191}=\frac{(191)\times h}{191}

126.2=h

Therefore, the width of the parking lot is 126.2 meters.
