Answer:
21 child tickets
Step-by-step explanation:
For this problem, you'd use a system of equations.
First, define your variables.
x = # of child tickets sold
y = # of adult tickets sold
There were 4 times as many adult tickets (y) as child tickets (x) sold, so:
4 x = y
4 x - y = 0
93 (4 x - y = 0)
372 x - 93 y = 0
The total revenue was $909.30, adult tickets were $9.30 each, child tickets were $6.10 each, so:
6.10 x + 9.30 y = 909.30
10 (6.10 x + 9.30 y = 909.30)
61 x + 93 y = 9093
372 x - 93 y = 0
433 x = 9093
433 x / 433 = 9093 / 433
x = 21
2 numbers can be represented by the variables x and y.
Set up a system of equations:


The two numbers added together will result in a sum of 33. However, one number subtracted from another will result in a difference of 1.
In both systems of equations, there are inverses of variable y. Therefore, we can combine the systems of equations by adding them together:


Divide both sides by 2 to get x by itself:

One of the numbers will be 17.
Plug the value into one of the equations:

Add y to both sides:

Subtract both sides by 1 to get y by itself:

The two numbers that sum up to 33, with a difference of 1 between them, will be 16 and 17.

Answer: 
Step-by-step explanation:
- Dilation is a transformation, in which the size of the image gets changed but not shape.
The rule of dilation with scale factor k and wither origin as center of dilation :
(x,y) → (kx, ky)
Here ,
, center of dilation = Origin
Then, the rule best represents a dilation to create pentagon PQRST will be :
