Question

@mathmale Hello again!

Answer 1

And right of the start I do see the pun. BRAIN ~ POWEQ (Brain Power) @mathmale

Answer 2

@mathmale COME HERE OR DIE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Answer 3

nevermind

Answer 4

Oh?
:)
Since the two figures are similar (which doesn't require a lot of brain power to detect), then it's a fairly straightforward matter to determine the values of x, y and z.

I'd (arbitrarily) start by writing the ratio (7.5 / 3) and equate that to the ratio (17.5 / 14z), and then solve for z. Look carefully at the two figures and see whether or not this makes sense. You'll need to do similar operations to find x and y.

Answer 5

z=2?

Answer 6

@mathmale

Answer 7

I haven't actually done the arithmetic, but at first glance your z=2 looks reasonable. Would you please apply the same strategy to determine the values of x and y?

Then perhaps you and I working together could check your results.

Answer 8

So: we're going to assume, for now, that z=2.
Let's now try to find x.
I'd write (12.5 / (2x+1) and equate that to (10/4). Hope this makes sense. Try to figure out where these numbers and that expression came from. Find x.
Then do something similar to determine y.

Nick, as much as I'd like to help you all the way thru this problem, I really need to hit the sack. I'm driving from Helena, Montana, to Salt Lake City, Utah, tomorrow, and expect to be on the road all day. Best to you. MM
