Find the exact solution for \[\sqrt{5}-1/x =\sqrt{5}/2\] Then find the approximate solution to the nearest tenth.

OpenStudy (anonymous):

want to try first?

OpenStudy (anonymous):

@surdawi here it is i tried it and im so confused

OpenStudy (anonymous):

ok show me the steps you took this way i can explain it to you

OpenStudy (anonymous):

wait a sec my computer is acting crazy

OpenStudy (anonymous):

OpenStudy (anonymous):

i see it, but i cant see your work :D

OpenStudy (anonymous):

sorry but i dont know where to start to try to solve it

OpenStudy (anonymous):

ok, i'll show you

OpenStudy (anonymous):

\[\sqrt{5} - 1/x = \sqrt{5}/2\] subtract \[\sqrt{5}\] \[-1/x = \sqrt{5}/2 - \sqrt {5}\] times x \[-1 = (\sqrt{5}/2 - \sqrt {5})* x\] divide by \[ (\sqrt{5}/2 - \sqrt {5})\] \[\frac{ -1 }{ (\sqrt{5}/2 - \sqrt {5}) } = x\] \[x=\frac{ 2 \sqrt{5} }{ \sqrt{5} }\] x= 0.9

OpenStudy (anonymous):

well thats not one of my answers hold on and ill post them

OpenStudy (anonymous):

what are your answers? 0.89?

OpenStudy (anonymous):

\[10-2\sqrt{5}/5; 1.1\]

OpenStudy (anonymous):

thats A.

OpenStudy (anonymous):

\[2-2\sqrt{5};-2.5\]

OpenStudy (anonymous):

B

OpenStudy (anonymous):

c.\[-2;2\]

OpenStudy (anonymous):

d.\[2\sqrt{5}-2/\sqrt{5};1.1\]

OpenStudy (anonymous):

is the question \[\frac{ \sqrt{5} -1 }{ x } or \sqrt{5}-\frac{ 1 }{ x }\]

OpenStudy (anonymous):

the first one you put right there

OpenStudy (anonymous):

you always make me do double the work answer is \[\frac{ -2 \sqrt{5} }{ 5 } + 2 ; 1.1\]

OpenStudy (anonymous):

sorry :(

OpenStudy (anonymous):

what grade are you in?

OpenStudy (anonymous):

11th

OpenStudy (anonymous):

1 more yr and you will be in collage, so try to focus and try to solve these problems
