For problems 1-10, solve the given rational equation.

#1 i choose D- x=8/9
#1-

A x = 9/8
B x = 1
C x = 2
D x = 8/9
E x = 2x
F x = 4

#2-i choose B- k=20/3
#2-

A- k = 2
B- k = 20/3
C- k = 3
D- k = 3/20
E - k = 7
F- k = -1

#3-i choose f- n=11/4
#3-

A- n = 1/2
B- n = 11/2
C- n =1/5
D- n =1/4
E- n = 4/11
F- n = 11/4

For problems 1-3 (?), solve the given rational equation.

#1 I choose D --> x = 8/9
#1-
A) x = 9/8
B) x = 1
C) x = 2
D) x = 8/9
E) x = 2x
F) x = 4
-------------------------------------------------------------
#2 I choose B --> k = 20/3
#2-
A) k = 2
B) k = 20/3
C) k = 3
D) k = 3/20
E) k = 7
F) k = -1
-----------------------------------------------------------

#3 I choose F --> n = 11/4
#3
A) n = 1/2
B) n = 11/2
C) n = 1/5
D) n = 1/4
E) n = 4/11
F) n = 11/4

------------------------------------------------------------

for one thing, put in horizontal spaces and vertical
spaces for readability. And, taken literally, "Ax,...,
Ak,..., and An,... are meaningless here.

For another thing, I have *already* told you that you
don't type "[/math]" and "[math]" in the middle of
your equations, because the equals signs do not
expressed (in Latex.)

All of your *three* answers are correct.

***Edit:

In my opinion, your edit has helped very much.

hey reconsideryouranswer i edited what i did hope its right now and thank you

Hi zee-f;

How are you today? Where is 4 - 10?

zee-f · 2011-09-18 06:41:21

hey bobbym am not so good am stuck on number 4

Bob · 2011-09-18 06:56:34

hi zee-f,

I'm on-line. Do you want to post the question?

Bob

zee-f · 2011-09-18 07:12:56

hey this is the question

=5

like the lcm i think is 30

so do i multiply both sides by 30?

Bob · 2011-09-18 07:16:26

hi zee-f

You could do that but x6 is enough as the 5 is 5/1

So what do you get if you times by 6?

Bob

zee-f · 2011-09-18 07:21:36

i would get

18x+30=30

Bob · 2011-09-18 07:26:26

Bob

zee-f · 2011-09-18 07:29:40

ooh i would get

7x=30

so ill divide both sides by 7 ill get x=30/7

Bob · 2011-09-18 07:32:16

Yes! Correct!

Bob

zee-f · 2011-09-18 07:33:55

thank you so much

zee-f · 2011-09-18 08:20:12

i did number 5 this is what i got

#5-

A- x = 1/2
B- x = 1
C- x = 1/5
D- x = 3/7
E- x = 2
F- x = 3

i got A witch is 1/2

20x-4=6

add 4 to both sides

20x=10

divide 20 to both sides

x=10/20

x=1/2

Bob · 2011-09-18 08:23:14

That looks good to me.

Well done.

Bob

zee-f · 2011-09-18 08:26:37

thank you

Bob · 2011-09-18 08:31:30

Oh yes. About Latex.

You can put all of one line between the math /math tags eg.

makes this

Bob

zee-f · 2011-09-18 08:35:45

ooo thank you for that it took me a while to write all of that

Bob · 2011-09-18 08:40:02

and then I use copy and paste for the next line ... then just edit it to show what I really want next.

Bob

zee-f · 2011-09-18 09:49:54

hey guys i was wondering if i got this right

i got number 6 is f witch is -17/15

A -------> x = 17/5
B ------- > x = -21/15
C ------- > x = -7/5
D -------> x = -1/5
E--------> x = -15/17
F -------> x = -17/15

bobbym · 2011-09-18 09:55:17

That is correct!

zee-f · 2011-09-19 00:54:27

hey guys i did number 7 wondering if its correct
i choose A x=1

#7-

A---------> x = 1
B--------> x = 1/2
C---------> x = 2
D----------> x = 1/3
E-----------> x = 3
F-----------> x = 1/4

bobbym · 2011-09-19 01:04:49

Hi zee-f;

That is correct. Very good!

zee-f · 2011-09-19 01:10:49

thank you oooh 3 more to gooo!!:)

zee-f · 2011-09-19 01:30:02

hey i was wondering for this one whats the lcf???
