Answer:
90
Step-by-step explanation:
Create an equation where all the numbers are added together and divided by 6 to equal 80:
![\frac{72+86+92+63+77+x}{6} = 80](https://tex.z-dn.net/?f=%5Cfrac%7B72%2B86%2B92%2B63%2B77%2Bx%7D%7B6%7D%20%3D%2080)
Simplify and solve for x:
![\frac{390 + x}{6} = 80](https://tex.z-dn.net/?f=%5Cfrac%7B390%20%2B%20x%7D%7B6%7D%20%3D%2080)
![390 + x = 480](https://tex.z-dn.net/?f=390%20%2B%20x%20%3D%20480)
![x = 90](https://tex.z-dn.net/?f=x%20%3D%2090)

Answer:
It would take an hour to download a 2 hour movie.
Step-by-step explanation:
To find the amount of time it takes to download a 2 hour movie, you can use proportions.
14/42(since it takes 14 minutes to download a 42 minute TV)
Next, you want to find out how much a 2 hour movie takes. In order to do that, you first have to convert 2 hours into minutes.
60 x 2= 180(since there is 60 minutes in an hour)
then you place the proportion accordingly
14/42=x/180
The 42 and 180 represent the duration. The 14 was the amount of time it took for the show to download. x represents what we are trying to find.
Next, you cross multiply.
180 x 14= 2,520
42(x)=42x
To find the answer, simply do 2,520/42 to get 60.
This also equals an hour so therefore, it takes 1 hour to download a 2 hour movie.
