    What Number Should You Write to Win the 2/3rds Average Math Riddle?

    Good question, I don't know the answer, but for our purposes let's assume either. Either way, assuming everyone know's how to play the game, the answer should be 0, correct?

    What Number Should You Write to Win the 2/3rds Average Math Riddle?

    i really don't know the answer, it was a question from a lecture about numerical methods. but 0 seems logical, as long as everyone knows the rules. and i don't think people will write down uncomputable numbers...but I'm not quite sure what you mean by that, nateTG.

    What Number Should You Write to Win the 2/3rds Average Math Riddle?

    On the piece of paper handed out in class please write a number between 0 and 100. The winner is the one who comes closest to 2/3rds of the average of numbers written by the students of the class. Question: What number should you write?

    3 equations, 3 unknowns, how do i solve ?

    so now i have two linear equations: by - bx = c -y bz - bx = 7c - 7z which I'm not sure how set up from there as a linear eqn...should i factor a b out of the left side of the first equation then divide? please let me know! thanks

    3 equations, 3 unknowns, how do i solve ?

    okay so i have bx = a + d by + y = a + d + c bz + 7z = a + d + 7c where x,y,z are #'s and d=bc... if i want to put this in a matrix, is it possible? because i see the b's on the left side of the equation that are unknown... thank you for your patience.

    3 equations, 3 unknowns, how do i solve ?

    hmm I'm not sure i follow. so would i have xb = a + bc ? and then replace bc with d? how do i go from there then when i have xb = a + d? thanks

    3 equations, 3 unknowns, how do i solve ?

    3 equations, 3 unknowns, how do i solve!? hi everyone, i have 3 equations and 3 unknowns: x = (a/b) + c y = (a/(b+1)) + c z = (a/(b+7)) + c where x, y, z are given in the problem (real #'s), and we need to find the values of a, b, and c. can anyone tell me how to go about this...

    Anyone know of any good math scholarships or competitions?

    i would check your school or counselor and ask for some scholarship applications. the biggest piece of advice is always write very neatly and if possible, TYPEWRITE the application, which will let the scholarship committee know you are serious about the award.

    Unusual Connections: a, c, d, e, l, r, and x

    Highlight to see... These letters all have equal counterparts when written in capital cursive and captial script. These letters start with one vertical line in the 'e', then two with the 'l', and three vertical lines in the 'r' and 4 in the 'x' when written in lowercase cursive.
