Question

need help with this equation

5/(4 ) (3x-1/2)-2/(3 ) <7/3

Answer 1

When you are solving and you have denominators, it is best to multiply every term by the least common denominator--- it will get rid of all denominators for you..

Answer 2

Is the 2 under all of 3x - 1 or just under the 1?

Answer 3

5 over 4 times 3x - 1/2 - 2/3 is less than 7 over 3

Answer 4

So the least common denominator is 12 - so multiply every term by 12.

Answer 5

@Blexting only under the 1

Answer 6

looks like you have somone, good luck

Answer 7

12(5/4) = 15
12 * 3x = 36x
12* (-1/2) = -6
12 * (-2/3) = -6
12 * (7/3) = 28

Answer 8

Thx Schultzman8

Answer 9

5/4 times what (3x - 1/2) in the original?

Answer 10

ok i got 540x-90-6

Answer 11

I am wrong... didn't get the parentheses correct

Answer 12

yes @ 5/4 times what (3x - 1/2) in the original?
ohhh ok

Answer 13

god this class is killing me

Answer 14

15/4x - 5/8 -2/3 < 7/3

Answer 15

LCD = 24

Answer 16

thats what I got I just did not like the end result

Answer 17

24(15/4x) = 90x
24(-5/8) = -15
24(-2/3) = -16
24(7/3) = 56

Answer 18

according to my text from the chapter the 7/3 is to be done after I get the first part done

Answer 19

90x - 15 - 16 < 56
90x - 31 < 56
90x < 87
x < 87/90 (I don't like the answer either)

Answer 20

so it should look like 90x-15-16 < 7/3

Answer 21

If you multiply one of the terms by 24 you have to do it to all of them including the 7/3

Answer 22

No.. that would not be correct.. it has to be done to everyterm.
90x - 15 - 16 < 56

Answer 23

^he is right

Answer 24

90x-31<56

Answer 25

then times the the two denomanators 3x24

so I would have 90x - 15 - 16 < 72

Answer 26

gosh I am confused LMAO

Answer 27

90x<87 x would be a decimal

Answer 28

my instructor is a douch

Answer 29

so I got 0.966666

Answer 30

Above you had 72... it was 24(7/3) so 3 goes into 24 8 times and then time 7 is 56

Answer 31

remember, it is less than, not equal too

Answer 32

therefore x= .966 or less

Answer 33

Alright?

Answer 34

so the solution set would be {x|x< .966}

Answer 35

yes

Answer 36

THX to both of you I have one more problem if u have time...

Answer 37

alright, but can i get a medal?

Answer 38

it is the elimination method

Answer 39

of course
how do i do that

Answer 40

click good anwser for one of my anwsers

Answer 41

thankyou

Answer 42

5x+5y= -11
7x-2y=19

Answer 43

Now I will explain the Elimination method, to see if it helps you

Answer 44

I get x=1.62

Answer 45

I could not get Y cuzz i think x is wrong

Answer 46

When adding two equations, you basically add all parts of them. Say you had the equations:
5x + 5y = -11
7x-2y= 19

Answer 47

so 12x + 3y= 8

Answer 48

I have not had any problems using it with other problems i just did not like the answer I got for X

Answer 49

12x + 3y = 8.

Answer 50

If you have those two equation - you have to eliminate one of the variables.. so multiply the first by 2 and the second by 5

Answer 51

2(5x - 5y = 11)
5(7x - 2y = 19)

Answer 52

elimination method is when you elou to cancel out on variable

Answer 53

10x - 10y = 55
35x - 10y = 95

Answer 54

Oops 10x + 10y = 55
35x - 10y = 95

Answer 55

thats what I got blexting

Answer 56

Add them up
45x = 150

Answer 57

x = 3 1/3

Answer 58

the 11 is a negative

Answer 59

OOPS.. you are correct.

Answer 60

10x + 10y = -55
35x - 10y = 95

Answer 61

45x = 40
x = 40/45
x = 8/9

Answer 62

i got 73/45

Answer 63

ohhh ilike ur answer better then mine

Answer 64

5x + 5y = -11
5(8/9) + 5y = -11

Answer 65

40/9 + 5y = -11

Answer 66

ok os not iplug 8/9 into

Answer 67

4 4/9 + 5y = -11
5y = -15 4/9

Answer 68

but i still have a fraction how does that solve

Answer 69

I would do this instead.

Answer 70

5(8/9) + 5y = -11

Multiply every term by 9... it gets rid of denominators
40 + 45y = -99

Answer 71

45y = -139

Answer 72

y = -3 4/45

Answer 73

oh lord

Answer 74

well thx for all ur help my assignment ti lto mor rowil tomorrow so I will keep all ur advice in mind I could not have figured it out hithout both of ur help!!!!!
