Question

plz help

Answer 1

-3/5

Answer 2

thx

Answer 3

its 5/3

Answer 4

Wait its 5/3

Answer 5

(:

Answer 6

XD you were faster

Answer 7

tama did u get how to solve it?

Answer 8

no :(

Answer 9

ok 1st we have this->\[\frac{ 3 }{ 5 }x =12\]

and finally we have this->\[x=20\]

Answer 10

so basically the x is being isolated
ok?

Answer 11

to isolate x the 3/5 has to be removed

Answer 12

If you multiply 3/5 and 12 by 5/3 then you get 1 and 20, making the equation 1X=20 which is the same as X=20

Answer 13

yea

Answer 14

can u think of a way to remove the 3/5

Answer 15

subtract?

Answer 16

no

Answer 17

:( y not

Answer 18

if we subtract any term say T it will be like this-\[\frac{ 3 }{ 5 }x-T=12-
T\]and when we will simplify it further it will go like this-\[\frac{ 3x-T(5) }{ 5 }=12-T\]what do u think..is subtraction making things more easy or complicated?
is x likely to get isolated this way?

Answer 19

OH

Answer 20

so do u think subtraction will work?

Answer 21

no

Answer 22

ok now we try multiplication :)

Answer 23

do u agree to the fact that\[a \times \frac{ 1 }{ a }=1\]?

Answer 24

ok

Answer 25

thats confusing qwerty

Answer 26

ok i'll walk u through u keep responding tho

Answer 27

lol ok

Answer 28

\[a \times \frac{ 1 }{ a}=\frac{ a \times 1 }{ a}\]ok?

Answer 29

yup

Answer 30

we know that \[a \times 1=a\]

so \[\frac{ a \times 1 }{ a }=\frac{ a }{ a }\]

Answer 31

yup

Answer 32

overall till now we've done this-\[a \times \frac{ 1 }{ a }=\frac{ a \times 1 }{ a }=\frac{ a }{ a }\]

now what do u think is the value of\[\frac{ a }{ a }=?\]

Answer 33

1

Answer 34

wait nvm its a

Answer 35

no no
its 1

Answer 36

really isnt supposed to be a cause they r both a's

Answer 37

ok lets take an example
lets assume a to be 2

Answer 38

lol

Answer 39

what do u think is the value of \[\frac{ 2 }{ 2 }\] is it 2?

Answer 40

no its 1 cause they get a whole num of 1

Answer 41

yes
so now what do u think is the value of\[\frac{ a }{ a }\]

Answer 42

1

Answer 43

yea

Answer 44

:)

Answer 45

so now we have this-\[\frac{ 3 }{ 5 }x=12\]
we need to isolate x
and ofc we have to use multiplication its written in the ques

Answer 46

oh ok

Answer 47

yupppppppppppppppppppppp

Answer 48

i understand now

Answer 49

ok so what will u do next :)

Answer 50

u switch them to 5/3

Answer 51

then u multiply 5/3 with 20

Answer 52

jk

Answer 53

i meant 12

Answer 54

thats how u get 20

Answer 55

right?

Answer 56

yes :)

Answer 57

yay is it ok if u help me with more or r u busy

Answer 58

yea i can help

Answer 59

yay ok

Answer 60

did u try to do this one?

Answer 61

yea but i dont understand it

Answer 62

cause theres no answer to see if its right or not idk

Answer 63

ok :)
do u understand the concept of |x| ?

Answer 64

yup

Answer 65

that means like the exact
like if i had 12 then i would have to have a -12

Answer 66

no
its like u will always get a positive of the number\[|12|=12\]\[|-12|=12\]ok?

Answer 67

yea i mean i guess thats what i meant

Answer 68

ok so we can say that whenever we have something like |x| it will always be positive

Answer 69

lol

Answer 70

yuppppp

Answer 71

ok now u tell this-
If I say that \[|x|=-3\]what will u say

Answer 72

ugh qwerty u made it difficult>.<
i think thats it would be -3 and 3 cause the teacher tells us we have to choose 2 num

Answer 73

:( u left

Answer 74

no m still here

Answer 75

ok :)

Answer 76

(:
we just said that if u have anything like this->
|x| then it will always give something positive\[|x|=SomethingPositive\]

Answer 77

what your teacher must have said is this->
for example if ur given\[|x|=7\]then x can be 7 or -7 because\[|7|=7\]and\[|-7|=7\]

Answer 78

yea

Answer 79

ok so i asked u something-

what will u say if i tell u that\[|x|=-3\]

Answer 80

l-3l=3

Answer 81

right?

Answer 82

(:

Answer 83

well we know that\[|x|=SomethingPositive\]but here\[|x|=-3\]
-3 is negative so there is no such value of x that will satisfy the equation

Answer 84

oh

Answer 85

@rhettwalker14

Answer 86

i suck at math

Answer 87

the |x| always gives out the positive value
this is its wrk
it can never give something negative
so |x|=-3 is not possible
so no solutions

Answer 88

ok?

Answer 89

i dont get it

Answer 90

which part?
and @Tamara7301 ??

Answer 91

yes

Answer 92

so now we move towards solving the questions

Answer 93

1st u try to isolate the |x|

Answer 94

lol i get it
ok:)

Answer 95

i dont get all of it what is this anyway
