Make me two parts of 10 such that each part multiplied by itself, and the one multiplication taken from the other leaves 49. I ask what are the parts.
I ended up writing x + y = 10 x^2 + xy + y^2 = 49. That's not the right interpretation though. Apparently the correct approach is this: x^2 - y^2 = 49 Hint: "taken from the other" means subtraction somehow. Does it make sense, or do you find these word problems to be tricky too? --- I consider it completely unimportant who in the party will vote, or how; but what is extraordinarily important is this who will count the votes, and how. ...

I think they want the numbers for x and y, not your working out.

Makes perfect sense to me.

I got the correct solution before checking. That's clear enough to me.

two parts of 10
9+1=10 8+2=10 7+3=10 6+4=10 5+5=10 each part multiplied by itself, and the one multiplication taken from the other leaves 49 81 - 1 = 80 64 - 4 = 60 49 - 9 = 40 36 - 16 = 20 25 - 25 = 0 Must not be whole numbers 7.45 + 2.55 = 10 55.5025 - 6.5025 = 49 --- No locked doors, no windows barred.

Why are you guessing and checking? You have two unknowns and two equations. System of equations.

Because it was easier for me to set up a spread sheet in open office to solve it than it was for me to remember how to do math I haven't used in 15 years. --- No locked doors, no windows barred.

diff eq and linear algebra If you're talking about the hybrid class, then in my experience, that class is pretty easy as long as you read the book. --- Number XII: Larxene. The Organization's Savage Nymph. ... Copied to Clipboard!

I interpreted that correctly, though yes, the problem is poorly worded for no good reason.

I thought math was supposed to be about numbers. Not a stupid puzzle in an 80's point and click adventure game that will kill you anyway.
