Answer 16

That online calculator wont work '_' .

Answer 17

\[\frac{5.66}{y}+\frac{5.5}{4y}=4\]Multiply through by \(4y\)
\[4*5.66+5.5=16y\]Divide by 16\[28.14/16 = y\]\[y=1.75875\]

Answer 18

So you would replace the y var with 1.75?

Answer 19

i did exactly what whpalmer4 did, and that is correct, shouldnt have doubted myself lol, the calculator part though, does not work

Answer 20

@yummydum @whpalmer4, I can always count on you guys at the end.

Answer 21

The solution is the line y = 1.75875...which intersects one of the hyperbolas in the 1st quadrant

Answer 22

glad i could help

Answer 23

Could it possibly be negative though?

Answer 24

-1.75 is one of the choices

Answer 25

as far as i see, the answer should be positive
