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
Answer:
23.75
Step-by-step explanation:
X=27
You have to divide 4x=108 and you get 27!
Answer:
x = 42-degrees
Step-by-step explanation:
x + 48 = 90 --> *subtract 48 from both sides*
x = 42
There are 6 sides so that means that the angles add to 180(6-2) = 180(4) = 720 degrees
So let's add up the angles and set that result equal to 720. Then solve for n
Note: I'm starting at the angle n and working counter-clockwise
(n)+(140)+(151)+(62)+(135)+(n+6) = 720
n+140+151+62+135+n+6 = 720
2n+494 = 720
2n+494-494 = 720<span>-494
</span>2n = 226
2n/2 = 226/2
n = 113
So the final answer is n = 113
