Answer:
80 movies must be streamed.
Step-by-step explanation:
To find the average cost, you must divide the total cost by the number of movies watched.
When you watch 1 movie, you pay the initial fee of $80 plus a $4 purchase of the film.
The equation is shown as such:
average cost = (total cost)/(number of movies)
Your total cost can be represented as
, while the number of movies is represented as
.
You want the average to equal 5, so your equation is shown as follows:
![5 = (4x+80)/x](https://tex.z-dn.net/?f=5%20%3D%20%284x%2B80%29%2Fx)
simplifying this, we get
![5 = 4 + \frac{80}{x}](https://tex.z-dn.net/?f=5%20%3D%204%20%2B%20%5Cfrac%7B80%7D%7Bx%7D)
which can then be simplified to
![1 = \frac{80}{x}](https://tex.z-dn.net/?f=1%20%3D%20%5Cfrac%7B80%7D%7Bx%7D)
X = 80 movies.
Hi
First dont panic. this one is pretty easy.
you known that the perimeter is the addition of every sides of a figure.
you have the total perimeter : 84.6
so now you just have to withdraw every side you have to the total , and the missing measure will be the result.
have a try ! you can make it.

I'm doing okay i miss school and my friends
It takes 7 hours to mow 4 lawns
Therefore every hour, (4 ÷ 7) or 4/7 lawns are mowed. This gives the rate.
For 35 hours, 4/7 x 35 lawns are mowed.
=35 ÷ 7 = 5
= 4 × 5
= 20 lawns
You just add the negative sign -10934 meters
