Answer Please! I hate khan academy lol​
Zanzabum

Answer:

C; None of the above.

Step-by-step explanation:

Pretend x=1, y=0, and z=2.

You have to match an answer to 1+0-2 (equals to -1).

The first equation would be 2+0+1. When you add them all together you get 3, and that isn't equivalent to -1, so therefore this one is not the answer.

The second equation becomes 1+2+0, and when you solve for the answer, you see that the answer is also 3, and so we can conclude that neither A or B matches with the equation above, so the answer is C, None of the above.

The admission fee at a fair is $2.00 for children and $4.00 for adults.

On Saturday 2,500 people entered the fair and $7,000.00 were collected.

How many children and how many adults attended? Give your answer, using x for children, y for adults.

Form of: x =, and y =

 

Let K = no. of children

Let A = no. of adults

 

2500 people mean

Kids + Adults

 

K + A = 2500

K = 2500 – A

 

2K + 4A = 7000

K + 2A = 3500

 

(2500 – A) + 2A = 3500

A = 3500 – 2500

(A = 1000, adults)

 

K = 2500 – A

K = 2500 -1000

(K = 1500, Kids)

 

CHECK:

1500*2 = $3000

1000*4 = $4000

<span>(Total = $7000, people.). </span>

<span>
