Chris and Mary are selling tickets at their class play. Chris is selling student tickets for $4.00 each, and Mary selling adult tickets for $6.50 each. If their total income for 21 tickets was $124.00, how many tickets did Chris and Mary sell individually?

Answers

Answer 1

Answer:

Chris sells 5 tickets and Mary sells 16 tickets

Step-by-step explanation:

System of Equations

To solve the problem we call:

x = number of tickets sold by Chris

y = number of tickets sold by Mary

They sold a total of 21 tickets, thus:

x + y = 21 [1]

Mary sold adult tickets for $6.50 each and Chris sold student tickets for $4.00 each. The total income was:

4x + 6.5y = 124 [2]

Multiplying [1] by -4:

-4x - 4y = -84 [3]

Adding [2] and [3]:

2.5y = 40

Dividing by 2.5:

y = 40/2.5

y = 16

From [1]

x = 21 - 16 = 5

x = 5

Chris sells 5 tickets and Mary sells 16 tickets

15pts. Please Answer, Im Checking If I Am Correct Is It 8.40? A box of 100 sanitizing wipes costs $12 . How much does one wipe cost?

Answers

Answer:

Each wipe costs .12¢

Step-by-step explanation:

I think you would have to divide $12 by 100 because the are 100 wipes and that equals 0.12

Answer:

$0.12

Step-by-step explanation:

One box of wipes contains 100, which costs 12 dollars.

The price for one wipe would be the total price, $12, divided by the 100 wipes. Therefore,

12 / 100 = $0.12 each

Ms. Erickson is going to see the hot air balloons in Albuquerque, New Mexico.

She found out that for every 5 balloons in the sky, 2 of them will be rainbow colored.

If there are 150 balloons in the sky, how many will be rainbow colored?

Answers

Answer:

Step-by-step explanation:

You have to multiply the top and bottom of the fraction (2/5) by 30 so the denominator will be 150. You also have to multiply the top by 30 (2 times 30). The answer is 60 will be rainbow colored!

2 x 30 = 60

5 x 30 = 150

Answers

Answer:

7 1/14

Step-by-step explanation:

198÷28 = 7.blablabla

Therefore, 7 is the integer

so you take 7 and multiply it by 28 = 196

198 - 196 = 2

Therefore, 2 is the remainder

The format for mixed numbers is Integer (remainder/denominator)

so the mixed fraction is 7 2/28

2/28 can be reduced to 1/14

Therefore the final answer is 7 1/14

Answers

Answer:

The answer would be "j"

Step-by-step explanation:

First, you would want to find the value of the original equation:

5(y + 2) + 4

Use order of operations and distribute the five.

5y + 10 + 4

5y +14

This is the value of the original equation

Now we can work through the other options, but because we already know the answer, lets see about that one.

5 x y + 5 x 2 + 4

Again, use order of operations.

Multiply first

5y + 10 + 4

and complete the equation

5y + 14, which equals our original equation.

What's the length of side AB in ∆ABC shown?
A. 5
B. √313
C. 6
D. √15

Answers

Answer:

The value of x = 5 units.

Step-by-step explanation:

Given the right-angled triangle ∆ABC with the following dimensions

AC = a = 12

BC = c = hypotenuse = 13

AB = b = x

Pythagorean Theorem

For a right-angled triangle with the sides, a and b the hypotenuse c is defined as:

[tex]c=\sqrt{a^2+b^2}[/tex]

Thus, using the Pythagorean Theorem to determine the value 'x',

[tex]b=\sqrt{c^2-a^2}[/tex]

as b = x, so

[tex]x=\sqrt{c^2-a^2}[/tex]

a = 12c = 13

[tex]x=\sqrt{13^2-12^2}[/tex]

[tex]x=5[/tex]

Therefore, the value of x = 5 units.
