dam thats a question
Just like a math teacher...lolX + XSquared + (7 + X squared)= 3.10
Thats the actual way that the problem reads. Its been a long time. But you are going to factor out the squares and get the square root of 3.10 then divide by the X's that are left and that should give you your answer. Man its been a long time. Look at your factoring out rules in the book. I'm close
Jkole did it but not sure how he got 17 without showing the work.
I would think that X = number of quarters.
Quarter QUAN. X Dimes QUAN 2X Nickles 2X+7 Total
$0.25 1 $0.20 2 $0.45 9 $0.90
$1.00 4 $0.80 8 $0.75 15 $2.55
$1.25 5 $1.00 10 $0.85 17 $3.10
$1.50 6 $1.20 12 $0.95 19 $3.65
Spreadsheets are great. X + 2X + 2X+7 = $3.10
I still can't figure out if I'm holding a 3 pound bass or a 9'er. I always round up! :biggrin:Holy Crap. And all I thought I needed to know was that 5 made a limit and if they were big enough I won.................You guys totally rock thats all I can say about that..........
That is half the fun, remembering how do apply those lessons. The 4 rules of algebra. We can have Del put a new forum on here, math brain teasers. My nephew was in the 8th grade and all last year I was pounding out some very strange problems.THAT IS RIGHT I SCREWED UP AND SQUARED THEM. THAT WILL MAKE IT EVEN EASIER TO COMPLETE. THAT WAS FUN.
