Question

One month, a music site observed that 60% of the people who downloaded songs from its site downloaded Q Sam's latest single. The equation below represents this information, where x represents the total number of people who downloaded songs from the site that month.

x = 0.6x + 384

How many people who downloaded songs from the site that month downloaded Q Sam's latest single?

Answer 1

Where do I start?

Answer 2

nvm i guess this works too

Answer 3

solve for x

Answer 4

What exactly do I do?

Answer 5

solve for x
by getting all the terms with x on 1 side

Answer 6

ur equation looks weird tho.. are u sure thats how it really is

Answer 7

x = 0.6x + 384
if this ur equation
and i set x = 0 then
0=384.. doesnt make sense

Answer 8

so it would turn into a negative X right? and yeah thats what it says right here on the website!

Answer 9

seems a little odd given the words that you have \(x\) on both sides of the equal sign, but no matter, you can go ahead a solve anyway

Answer 10

\[x = 0.6x + 38\\
.4x=384\\
x=384\div .4=3840\div 4=960\]

Answer 11

Where did you get the .4? sorry for asking lol I understand this is a very awkward problem lol

Answer 12

you start with
\[x=.6x+384\] to get \(x\) on one side of the equal sign, subtract \(.6x\) from both sides
\[x=.6x+384\\x-.6x=684\\.4x=384\]

Answer 13

typo there, but you get the idea right?

Answer 14

if the decimal annoys you you can always multiply both sides by 10 and get
\[10x=6x+3840\\
4x=6840\\x=3840\div 4\]

Answer 15

I don't understand why they did not have this as a example iin the lessons xD But now I do get it...

Answer 16

maybe they had a problem like "solve for \(x\), \( 2x=6x+5\) "
but maybe not
