5x + 2y = 16 ⇒ 5x + 2y = 16
x + 3y = 12 ⇒ 5x + 15y = 180
 -13y = -164
 -13 -13
 y = 12 8/13
 5x + 2(12 8/13) = 16
 5x + 25 3/13 = 16
 -25 3/13 -25 3/13
 5x = -9 3/13
 5 5
 x = -1 11/13
 (x, y) = (-1 11/13, 12 8/13)

6 children and 2 adults are going to the circus. Children tickets are on sale,half price of adult tickets totaling $54. How much

Anon25 [30]

Answer:

Price of 1 adult ticket is $10.8 and Price of 1 children ticket is $5.4.

Step-by-step explanation:

Given:

Number of adults = 2

Number of Children = 6

Total Amount of tickets sold = $54.

We need to find the price of one children's ticket and one adult ticket.

Solution:

Let the Cost of 1 adult ticket be 'x'.

Now Given:

Children tickets are on sale,half price of adult tickets.

Cost of 1 Children ticket = $\frac{1}{2}x$

Total Amount is equal to Number of adults multiplied by Cost of adult ticket plus Number of Children multiplied by Cost of Children ticket.

Framing in equation for we get;

$2x+\frac{1}{2}x\times 6=54\\\\2x+3x=54\\\\5x=54\\\\x=\frac{54}{5} = \$10.8$

Cost of 1 adult ticket = $10.8

Cost of 1 children ticket = $\frac{x}{2}=\frac{10.8}{2} = \$5.4$

Hence Price of 1 adult ticket is $10.8 and Price of 1 children ticket is $5.4.

Can anyone help with the question ! Thanks <3

Artist 52 [7]

Answer:

26, 42

Step-by-step explanation:

2, 4, 6, 10, 16

This sequence is $a_n=a_{n-1}+a_{n-2}$ ⇒ the next term is the sum of the previous 2 terms.

Therefore, the next 2 numbers in this sequence would be:

10 + 16 = 26 and 26 + 16 = 42

The midpoint of K is M(-3, -1). One endpoint is J(-12, -11). What are the coordinates of endpoint K?

Over [174]

Answer: 2 times sqrt(181) (approximately 26.9)

Step-by-step explanation:

First, we can plot these points on a graph. Then, we’ll use the Distance Formula to calculate the distance between the two points, which is sqrt(181).

Since the problem tells us that one of our coordinates is the midpoint of K, we know that the length of the segment we just calculated is 1/2 of K. We can multiply our answer to get that K is 2 times sqrt(181).
