i need help with this question..

OpenStudy (anonymous):

OpenStudy (anonymous):

\[25-\frac{ 3 }{ 7 }f=19+\frac{ 4 }{ 7 }f\] bring like terms 2gether

OpenStudy (anonymous):

add 3/7 f on both sides

OpenStudy (anonymous):

how do you add a fraction?

OpenStudy (anonymous):

\[25-\frac{ 3 }{ 7 }f+\frac{ 3 }{ 7 }f=19+\frac{ 4 }{ 7 }f+\frac{ 3 }{ 7 }f\]

OpenStudy (anonymous):

take LCM

OpenStudy (anonymous):

huh :(

OpenStudy (anonymous):

\[25-19=\frac{ 4 }{ 7 }f+\frac{ 3 }{ 7 }f=\frac{ 4+3 }{ 7 }f=\frac{ 7 }{ 7 }f =f\] f=6, does dat help?

OpenStudy (anonymous):

u got common denominator in fraction just add the numerator

OpenStudy (anonymous):

i guess...

OpenStudy (anonymous):

kewl ;)

OpenStudy (anonymous):

thanks :) i'll try to firgure it out

OpenStudy (anonymous):

ur welcme ;)

OpenStudy (anonymous):

OpenStudy (anonymous):

:)

OpenStudy (anonymous):

;)

OpenStudy (anonymous):

@lovemenplayhard help please :( 4c + 7 + 6c =23

OpenStudy (anonymous):

do i subtract here?

OpenStudy (anonymous):

add like terms 4c+6c+7=23 10c+7=23 subtract 7 both the sides 10c+7-7=23-7 10c=16

OpenStudy (anonymous):

later divide both da sides by 10\[\frac{ 10 c}{ 10 }=\frac{ 16 }{ 10 }=\frac{ 8 }{ 5 }=c\]

OpenStudy (anonymous):

does dat hlp?

OpenStudy (anonymous):

so last one i divide 8/5?

OpenStudy (anonymous):

it's 1.6 ?

OpenStudy (anonymous):

finaly ur gonna get c=1.6

OpenStudy (anonymous):

but its not one of the answers, how could it be 1.6?

OpenStudy (anonymous):

16/10=1.6 or 8/5

OpenStudy (anonymous):

hmm okay then i guess its not one of them :/

OpenStudy (anonymous):

wat r ur options?

OpenStudy (anonymous):

A. Not given B. c =18 B. c = -8 C. c = -18

OpenStudy (anonymous):

A

OpenStudy (anonymous):

okay thats what i thought too :P

OpenStudy (anonymous):

kewl ;)
