Hello everyone

Plz have a look on this question http://dev-studyhall-novelguide.pantheon.io/question/x-5-190-what-value-x

this is my answer if anyone has another please post it :)

5% mean 5/100
equation will look like this : x - 5/100 = 190
to make it easier you simplify 5/100 = 1/20
then inverse opperation = 190 + 1/20 = 3801/20
this is your answer = 3801/20
need it in decimals : 190.05

Hello friends

hi

Henry

x - 5/100 = 190 => x - 0.05 =190 => x = 190.05

(off topic : did you know I was studying shaksphear's story about henry !! lOL)

hi lily

hi

oh :) from which novel

henry V (is that what you mean?)

hi henry

Your ans is incorrect :( :(

yes lily.

why even if you search it on an online calculator you will find the same answer ! I just searched it now

(no offense)

it is not calculated by any calculator :)

plz concentrate on it

henry that's cool it feels like talking to the character in the story

oh lori .. but it's answer is 190.05

hmmm tricky question

no it is, Lori , online calculator means it gives you answers with steps for your question

answer is 200 u right

b/c the 5% of 200 is 10

so x - 10 =190

hi maria

from were did you get 200 Maria?

hello maria

i think u r on right track

:)

hello

hi

:)

lori right i his question

200 is answer

ya okay but how did you get it???

hmm how it possible maria

i will try to prove

Do not tell me answer is 200,

lori words

i will prove it . wait a sec

it is so tricky

ok maria

Ok take your time

hmm

answer can't be 200 I just did some research and all saying it is 190.05

(and this was my answer ) yes, it is true take your time :) no offense

lily u r right .. i try it again and again but can't find the answer 200

im waiting for the answer 200 :)

hahahahah

5% of 200 is 10

ya !!! I know !!

so x- 10 = 190

I am taking this lesson and I know what I'm saying

x = 190 +10 = 200

just wait i will prove

how did you get the 10?

hello

what is a question ?

plus you're dealing with percentage how did you remove the 100 ??? and get the ten ??

hi

Aliza

190.05

Hi hanna

190 + 1/20

since we simplified 5/100

lori ?

5%=x of 5%

no hanna answer is 200

Maria can u proof?

Maria you did not prove it yet

yah almost

im just thinking about it but 200 is not possible

i will lili

So plz post your ans

190x1 = 100%... so 190+05% is 190x1.05

maria

I think lori and maria should redo it from the begining

and think more !! ;)

hahaha

;)

if i wil prove it so ?

???

lili so u can start your study at begining

Maria, we are 4 having the same answer, I have answered this twice and tried it twice , you cant say 4 are wrong and two are right !!

lili is right

as I mentioned before I answered these problems a lot so I know it !!!

plus you can't say all internet is wrong and only two are right (since the internet supports our answer

no I told you WE ARE 4 plus the Internet agrees with us so you can't prove yyour answer to us but we proved our answer to you so 4 are defiantly right and two are defiantly wrong, no offense but you have to understand this

but no budy is right all the time, and now today you are wrong lili :)

yes you are right but we are 4 saying the same answer !!!!

just check !!!

Yah i know but you know in a school 1 student is a first position holder not all

maria don't waste your time

200 is not a correct answer

4 and Internet with evidence to the answer , 2 with no evidence,

what you say????

200 is not correct

plz proof if u said this

yes !!

don't you worry i will prove it

Maria I'm not against you, but it is just a math problem that you think you are right and 4 plus INTERNET ARE RIGHT and you're not

maria answer

Maria 4 ppl at a time are not wrong

waiting....

:)

by the way Ans is 200

I said so millions of times but let's wait and see.........

let's wait for two more hours :) (JUST KIDDING ) .... I DON'T MEAN ANYTHING, JUST JOKING

I know we are waiting but we can't wait seriously we can just do anything else until they make there support

Guys, take a look plz
If x=200

therefore 5% of x =200x5/100

200 - 5% of x

200 - 10 =190

I searched everywhere and my own work, everything is just right here

190 = 190
LHS = RHS

why 200 x 5/100? from where did you get 200 ? it is not even involved in the quation

Lori i can't understand it

Lori i can't understand it

Lori i got your point

:)

not right

Lori answer my question: why 200 x 5/100? from where did you get 200 ? it is not even involved in the quation - See more at: http://dev-studyhall-novelguide.pantheon.io/forum/mathematics#sthash.qrXrHUv0.dpuf

Im not understanding this
200 - 5% of x

It is incorrect

ya

lily is right

Henry plz focus on each and every step

every step is more clear

im enable to understand it :(

no Maria !!! you can't answer my question !! then you are wrong

Im also enable to understand the point which is marked by henry

Lori plz expalin the line 200 - 5% of x

why 200 !!! not in the equation at all !! okay !! does this make sense !!!

im not lily

it make sense

lori explain it clearly

what is wrong with this question

how did you get the 200 then It is not envolved at all in the equation ???

it is a simple question

lily and henry both are right

Maria just explain it plz

just putting the 200 in place of x

and every thing will be clear

plz do

it

Lori what u say

how to calculate it ?

why 2oo ?? It doesn't make sense because 200 is not part of the equation, even if you add or do anything with equation num. !!!

hmm maria im focused on it . i think u r right

maria are you prove it or not

in other words if you put 200 - 5% it will = 199.95 but the equation tells you you need the answer to be 190 !!

so 200 is wrong

know its the time for answer

oh thank God

hahahahhaah

:)

if you put 200 - 5% it will = 199.95 but the equation tells you you need the answer to be 190 !! ??? so answer is 190.05

i m so frustrated

plz answer

same here

ok ok aliza

be cool

Maria, concentrate on the last thing I said okay !!

lori you say

x - 5% = 190

right

lori ?

yes this is the equation

but where is lori

yes it is

I don't know he is away

now answer it

so Now maria put 200 in place for x

what you get

another num. than 190 right?

and 5% = x of 5%

but you want 190!!!

right

no use for multiplication since it tells you subtraction !!!

now put 190.05 - 5% what you get

lili wait i m answer to lori

yes it is

she want's 200 answer and i can prove it

on Calculator you get 190

so this is right

maria answer fast

plz expalin your point of view mariA

190.05 - 5% = 190 so the for of us are right !!

so

x - 5% = 190 then

Hence: 190 is equal to 95% of x

understand

Yes u r rite maria :):)

maria focus

lili are you agre

How maria

put your answer in place for x and see what you get

do it fast because I am tired

beacuse 5% = 5% of x

hmm plz

if you get your answer 190 then your right but if you did not then you are wrong

ok thn

yes

95%x = 190

95%x = 190

plz maria proof it

lori got it?

HENRY SHE IS TRYING TO DO IT

Maria can you please do what I am telling you to, this will help you please !!!

Oh i got it

100%x - 5%x =190

95%x = 190

95/100 x = 190

you mean to say x -5%= 190 => 100%x - 5%x =190

oh ok i got it

0.95x = 190

x = 190/0.95

x= 200

:) oh great

no

:p

I mean you think 200 is your answer right?

Yes u r rite maria

yes i prove it

this is a correct sequesnce to solve ot

it

:)

thank u maria

right/ maria

unfortunately she is right lili

no can't be

I mean, ...

wlcm lori

lili know u are alone

remember your words

4 is agree and 1 you are not

so who is wrong

:)

okay did you put 200 in place fo x

well lets see

200 place it for x

this question is asked by my friend and i solved it in 4hours :p

200 - 5% of x = 190

5% of x = 200*5/100 = 10

no 200 - 5% =

200 - 10 = 190

190 = 190

199.95

okay you need this answer to be 190

and it is not so, if you put 190.05 you will get 190

why 10?

lili

why multiplication?

:)

okay give an explanation and I will listen

why you can minus

because equation says so

this is to check answer

i eill prove it and the questionar understand it

hmm lili is right :(

Maria u r rite

thanks for your expolanation

:)

hmm maria is prove it right

Ok maria i understand what u say

wlcm lori

:)

so explain it Maria to me ??

why multiplication?

by the way i am going to study at beginning lili :P

lili still not agree with your answer

I don't understand your answer ?

can you explain it?

i m already explain it lili

Yes plz expalin it.

ya I did not understand

why multiplication

my teacher told me to do it the way I did it why you did that way ?

why the online solver says the same answer I made?
