Question

Find an exact solution for.....

Answer 1

Then find the approximate solution to the nearest tenth

Answer 2

How did you get that answer?

Answer 3

@AngelCriner she found it by cross multiplying

Answer 4

ohhhh, so that answer is correct?

Answer 5

correct.

Answer 6

That's not one of the answer choices though

Answer 7

can you write out the question one more time, try to use the equation editor instead

Answer 8

\[\frac{ \sqrt{5} -1 }{ x } = \frac{ \sqrt{5} }{ 2 }\] :D I DID IT ! lol, but yea, that's the question :]

Answer 9

good job!
ohh so i think that was the issue... she thought the 5-1 was all under a radical

Answer 10

so you would still cross multiply
\[\frac{ 2\sqrt5-2 }{ 5 } \]

Answer 11

is that one of the answers?

Answer 12

Thank you and no, not necessarily. Want me to show you them?

Answer 13

are they in decimals?

Answer 14

Answer 20

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

Answer 21

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

Answer 22

C. \[-2 ; 2\]

Answer 23

D. \[ \frac{ 2 \sqrt{5}-2 }{ \sqrt{5} } ; 1.1\]

Answer 24

D. @AngelCriner

Answer 25

How'd you get that? and thank you

Answer 26

just cross multiplying and i did it wrong the first time
\[\frac{ \sqrt{5}-1 }{ x }= \frac{ \sqrt{5} }{ 2 }\]
\[\frac{ 2[\sqrt{5}-1] }{ \sqrt{5} }=x\]
\[\frac{ 2\sqrt{5}-2 }{ \sqrt{5} };1.1=x\]
