Question

I need some extra brainpower for this:

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


(WHAT IVE WORKED OUT):

X = 100% Of people who downloaded songs from a website

0.6 [times] X = 60%

60% + 384 = 100%


Choices:

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

A. 576
B. 240
C. 144
D. 960

Answer 1

x = 0.6x + 384
-.6x -.6x
-----------------
.4x = 384

what should x be?

Answer 2

96

Answer 3

almost .. you forgot a 0

Answer 4

384/.4 = 960

Answer 5

!!!!

Answer 6

You mind

Answer 7

helping out on some others

Answer 8

dunno, i havent seen the others ... they might scare me

Answer 9

heres one

Answer 10

Solve for :
x + 20 / 2 = 3x

Answer 11

use your grouping symbols correctly ... im assuming (x+20) is on top?

Answer 12

yes

Answer 13

what is your thoughts then, how would you try to work this?

Answer 14

Ill show you

Answer 15

Wait... Ima do this on notepad

Answer 16

I know that you first have to single x out onto 1 side of the line, but what confuses me is the
division thing. I know with division you have to find a Least common denominator, but since there is only
one division problem here, Im clueless as how to go on.

Answer 17

whatever we do to one side, we do to the other ....

A/2 = B ... in order to UNDO division, we multiply

2A/2 = 2B

A = 2B

Answer 18

i would start out by multiplying both sides by that denominator

Answer 19

So multiply both sides by 2 and get rid of the 2 on the first side?

Answer 20

yep

x+20 = 2(3x)

x+20 = 6x ... now what are your thoughts?

Answer 21

There is an x on both sides, so you have to get them onto one side.
Which side do I choose?

Answer 22

either side works ... personally is move the leftside over but it doesnt matter

Answer 23

20 = 5x?

Answer 24

subtraction UNDOES addition soo

x+20 = 6x
-x -x
-----------
20 = 5x

yes, now what is our x value?

Answer 25

4

Answer 26

correct

Answer 27

woww

Answer 28

if we had options, we could have also tried them to see what worked

Answer 29

I have one more. You wanna help pal?

Answer 30

one more, fine

Answer 31

Here I will snip and send pic

Answer 32

i few things wrong with this ... some would contend that this is cheating on an exam; but the more important thing is that you have posted personal information that is contained in the picture.

Answer 33

anyways, you know how to distribute?

Answer 34

Its no exam, XD Its a module test.

Answer 35

3x + 3 = -2x - 2 + 6

Answer 36

mrs collins, santiago, seminole county ... none of that needs to be posted publically is all. its a safety issue for minors

Answer 37

-2(-1) is not -2

Answer 38

dont forget your negative rules :)

Answer 39

Seriously? I could give out my homestate and city, there would still be about 1000+ collins and Santiagos to pick fro. That and you dont even know my address.

Answer 40

3x + 3 = -2x + 2 + 6

now what?

Answer 41

ANYWAYS

Answer 42

3x + 3 = -2x + 2 + 6

3x + 3 = -2x + 8

3x = -2x + 5?

Answer 43

so far so good, now add 2x to get rid of the -2x and we should be good

Answer 44

3(x + 1) = −2(x − 1) + 6.

3x + 3 = -2x + 2 + 6

3x + 3 = -2x + 8

3x = -2x + 5?
+2x +2x

5x = 5

x = 1

Thanks pal! :D

Answer 45

good luck :)
