Answer: The price for one adult ticket is $10 and the price for one child ticket is $7.
Step-by-step explanation:
<h3>
The correct exercise is: "At a movie theater, the price of 2 adult tickets and 4 children tickets is 48$. The price of 5 adult tickets and 2 child tickets is 64$. What is the price for one adult and one child?"</h3>
Let be "a" the price (in dollars) for one adult ticket and "c" the price (in dollars) for one child ticket.
Set up a System of equations with the data given in the exercise:

You can use the Elimination method to solve the System of equations:
1. Multiply the second equation by -2.
2. Add the equations.
3. Solve for "a".
Then:

4. Substitute the value of "a" into any original equation.
5. Solve for "c":

Answer:
$121.82
Step-by-step explanation:
Okay, this is kind of complex, so let's go step by step.
First, we want to find the area of the rectangular lawn - we can do this by multiplying the length and width. The length is 100 and the width is 45 so
m² is the area of the rectangle.
However, there are 3 ponds in which the grass seeds will not be going - so we need to find the area of all 3 of these circles and subtract it from 4500 (our rectangle area).
The area of a circle is represented by the formula 
The diameters are given here, which is double the radius, so to find the radius of each circle let's divide the diameters by 2.
First circle's radius: 
Second circle's radius: 
Third circle's radius: 
Now let's find the area of each circle.
<em>First Circle</em>: 
<em>Second Circle</em>: 
<em>Third Circle:</em> 
Adding all of these values gets us 412.125.
Now we can subtract from this from 4500 to get us 4087.875
If the grass seeds that cost £1.49 cover 50m² each, then we need
bags.
Each bag costs £1.49, so the total cost is 
Hope this helped!!

If you would like to find the number which belongs in the blank to complete the square, you can calculate this using the following steps:
f(x) = 5(x^2 - 4x + a) + 15
a ... the number = ?
<span>x^2 - 4x + a = (x - 2)^2 = x^2 - 4x + 4
</span>a = 4
The correct result would be 4.
Answer:
18 weeks
Step-by-step explanation:
Initial amount stored in savings account = $700
Final minimum amount required in the account = $150.
Thus,
The total amount of money he can spend = (700 - 150) = $550
Each week he is withdrawing $30 to go out to eat.
Since , maximum money he can spend should be multiple of 30 ,
Thus maximum he can spend $540
number of weeks he can do this = 
= 18.
So, he can take out $30 each week to go out to eat for 18 weeks only.
