Answer:
880 high-quality version
Step-by-step explanation:
I think the below is your full question:
<em>A Web music store offers two versions of a popular song. The size of the standard version is 2.1megabytes (MB). The size of the high-quality version is 4.5 MB. Yesterday, there were 1290 downloads of the song, for a total download size of 4821 MB. How many downloads of the high-quality version were there?</em>
Here is my answer:
Let x is the number of high-quality version
So the number of standard version= 1290 - x
We also know: total download size of 4821 MB. which means:
4.5x + 2.1(1290-x) = 4821
<=> 4.5x+2709-2.1x=4821
<=> 2.4x=2112
<=> x=880
So there were 880 high-quality version
We have to write a proportion. We put 35 over 60 to show that 35 miles can go in every 60 minutes. Next to it we write another fraction and put 490 over x because we are trying to find how many MINUTES first. we multiply 490 by 60 which is 29400. Now we divide that by 35. we get 840 minutes. Now we convert this into hours by dividing it by 60 because there are 60 minutes in an hour. 840 divided by 60 is 14 hours. The answer is 14 hours.

Step-by-step explanation:
To solve this, you simply need to divide 96.58 by 22. The reason you do this is so that way you can divide all of the weight into 22 bags.
96.58 ÷ 22 = 4.39
This means that the weight in each bag is 4.39lb.
