One month Ashley rented 2 movies and 5 video games for a total of $33. The next month she rented 8 movies and 3 video games for
Ray Of Light [21]

To answer this question, you should set up and equation before doing anything else. So for this question you 're going to set up two equations.

The first equation is 2x+5y=33

The second equation is 8x+3y=30

Once you do that you have to solve for either X or Y by canceling out the other one. In this problem figuring out the Y is easier because you can cancel the X's more easily than the Y. To cancel a variable, they have to add up to 0.

So to cancel the X you multiply the equation 2x+5y=33 by -4.

That gives you -8x-20y= -132

Then you set up the two equations and add them together.

(-8x-20y= -132) + (8x+3y=30)

That gives you -17y = -102

So then you solve for Y by dividing by -17. You find out that Y is equal to 6. Then you plug the 6 back into the ORIGINAL equations and solve for X, which turns out to be 1.5

Hope this helped and if you get confused or have questions please ask :)

The sum of the inner angles of a polygon with n sides is 180(n-2)

Since your polygon has 6 sides, the sum of its inner angles has to be

180(6-2) = 180 \cdot 4 = 720

On the other hand, the sum of its inner angles is

75+132+113+108+160+x = 588+x

And it has to be 720, so we have

588+x=720 \iff x = 720-588 = 132

The cost C (in dollars) of producing x DVD players is represented by C = 4.5x2. How many DVD players are produced if the cost is
lisabon 2012 [21]

Given the following equation representing the cost of producing DVD Players:

\text{ C = 4.5x}^2

Let's determine the number of DVD players produced if the cost is $544.50

\text{ C = 4.5x}^2\text{ \$544.50 = 4.5x}^2\text{ }\frac{\text{\$544.50}}{\text{ 4.5}}\text{ = }\frac{\text{4.5x}^2}{\text{ 4.5}}\text{ 121 = x}^2\text{ }\sqrt{\text{121}}\text{ = }\sqrt{\text{x}^2}\text{ 11 = x}

Therefore, it'll cost $544.50 to produce 11 DVD Players.

The answer is 11.
