that is better
this is an absolute value equation so it requires solving two separate equations

so you pretend the absolute value sign is not there?

for one of them yes, but you have to solve two all together

you get 2a=0

right
which means \(a=?\)

yes !
now on to the next equation

the next one is \[2a+1=-1\] again subtract 1, what do you get?

2a=-2

right, and now divide by 2

A=-1

yes
lets recap

so on a graph it would look like |dw:1439951388453:dw|

those two numbers, yes

okie tysm

yw

oh lol ic

can u help me with another question?

sure

as long as it is not statistics or geometry

yeah no its not

-3a+4=-14

no absolute values this time right?

a) subtract 4 from both sides
what do you get?

-3a=-18

ok good
now divide both sides by \(-3\)

a=6

bingo

omg tysfm ur so smart

lol you are quite welcome

i suck at math xD

actually you do not

can i ask u some more questions?

shoot

twelve is added to the product of a number and 5. the result is -3. find the number

ok here we need to translate in to math
product means multiply

so we pick a variable, or rather you pick one that will be "a number"

lol you have no imagination, i would have picked \(\xi\) but we will use \(x\)

the "the product of a number and 5" will translate as \(5x\)

idky but ur making me want 2 actually learn

imagine!

now we add\(12\) to \(5x\) to get what?

5x+12? or 17x?

first one

okay

\[5x+12x=17x\] but \[5x+12=5x+12\]

now you are told that this give you \(-3\) so final job is to solve \[5x+12=-3\] takes two steps

subtract 12 witch gives u 5x=-15

yup
next?

then divide 5 and u get x=-3

ok i guess you are really not so "bad at math" after all

lool

at least not as bad as i was

u used 2 be bad at math?

im shocked

look, it is not like you are born knowing this
you have to practice is all

ic ic

you got more, or are you done?

i have a few more

go ahead and ask if you want, or try them and ask
btw who does homework in the middle of august?

its a summer packet

kk get you ready for fall

wow

so much typing my fingers hurt

guess we need a variable again
guess we can recycle \(x\) as the amount of her original paycheck

i needa finsh this by 2day so my dad can unblock vantage smh

lolol!!!

fantage*

this is so laggy i have 2 keep refreshing

yeah i see that too

ok lets start with the amount cashed as \(x\) and start spending money

first spent $10 so has \(x-10\) left
then spend another 30 so what is left now?

x-40?

right
now here comes the confusing part

she spends half of that next, in other words half of \(x-40\) do you know what that is?

um 20?

you forgot to take half of \(x\)

so x-20?

you know, i have a much much better idea, lets approach this from a different way

okay

start at the end, and work backwards

in other words, what is \(17.75+29.45\)?

47.20

yeah that is what i get

94,40

i mean 94.40

yeah right both times

now add the reaming two amounts she spent

134.40

looks reasonable

it is nice to do algebra without variables
in math it is called "arithmetic"

lol

i have 4 more questions do u still wanna help me with them?

sure

$15 per answer

$25 for correct ones

just kidding, go ahead lets see them

im poor asf

lmfao

okay

|dw:1439953689890:dw|

man is that ugly

lmfao fr

thats a 0 not a d js

add \(C\) to both sides, which really just means write it

\[\frac{A}{B}x=D+C\] in other words

oh ic ic

by which i mean put parentheses about the \(D+C\)

so \[\frac{ b }{ a } *\frac{ a }{ b }=(d+c)\frac{ b }{ }\]

\[\frac{ b }{ a }\] *

something like that

\[\huge x=\frac{b}{a}(c+d)\] looks somewhat more professional

lol okay ty

yw

3 more until fantage?

mhm

you tell me
is going from 55 to 44 an increase or a decrease?

decrease

ok so we got that out of the way
now lets compute the difference
what is \(55-44\)?

ok now compare to the original amount of 55 by division,i.e compute \[\frac{11}{55}\]

0.2?

right, and now turn it in to a percent by moving the decimal two place to the right

20% decrease

yes

two more

wow okay

???

huh?

ballons not balling lmfao

and yea ballons

omg autocorrect

sorry for the misspelling

i think either there is not enough information or your answer has to have a variable in it

or we can assume that the number is 12 to begin with

lets say she starts with half of 12, which is 6 balloons

3 pop, how many left?

inflates 5 more
now how many?

??

report you? i don't even know you!

i dont report, i just ban
bye

ok now 2 pop
how many left?

now 6 get carried away
how many now?

nuffin

right

then inflates 16

i feel bad for the clown

which is 4 more than the 12 needed

not a good job i imagine

lol

brand new??!!

okay the last one has 2 do with geometry

not so good at that

okay ill do that one on with my brother he's good at math

ok good luck !!

okie tysfm for everything

you are quite welcome
see you again some time i am sure

lol yea buh byez
