try sosmath.com  they helped me before. if they don't have the answer you are looking for they have a list of links to tons of other math sites.  \n\nand there probably is someone on your campus that can help as well.  One on one help is always best...\n\nGood luck!

ignore the decimals when u originally do the problem, then however many deciams there are in both of the decimals you're multiplying is how many there will b in the answer. i.e. if you multiply 6.78x4.234 together the answer will have 5 numbers behidnthe dceimal point

***************\nQUESTION 1\n***************\nOn the first question, we first have to find the equation that we will be solving for.  \n\nAssume that x is one integer.\nWe know that x+1 is the other integer because they are consecutive.\n\nSo we now put the wording into an equation\n1/3(x + (x+1)) = x - 5\n\nNow we solve the equation\n1/3(2x + 1) = x - 5\n2/3x + 1/3 = x - 5\n16/3 = 1/3x\n16 = x\n17 = x + 1\n\nOur two integers are 16 and 17.\n\nNow we check our answer.\n1/3 of 33 = 11 & 16 - 5 = 11 We are good! :)\n\n\n***************\nQUESTION 2\n***************\nEvery hour, Amy and Randy together walked 3.6 + 4.2 km apart from each other.\n\n3.6 + 4.2 = 7.8\n\nSo, every hour they will be 7.8 more km apart from each other.  We only want 10 minutes though, and there are 60 minutes in an hour. To get how far apart they will be in 10 minutes, we take:\n7.8 * 10/60 = 1.3\n\nRandy and Amy will be 1.3 km apart after 10 minutes.\n\nWe are done! :)

Let x be the number of cookies.\n\n(1/3)*x + (2/9)*x + 4 + 8 = x.\n\n(5/9)*x +12 = x\n12 = x-(5/9)*x\n12 = (4/9)*x\n12*(9/4) = x\n27 = x.

in the first bowl, two people each take 'x' amount.  if you add them up you get x+x=2x.  therefore the amount that remains in the first bowl is 1-2x.\n\nin the second bowl, you have 3 people taking different amounts, taking x% of what remains in the bowl.\nlets assume the first person takes x amount\nthe second person takes x amount of what is left (1-x), or x(1-x) or x-x^2\nthe third person takes x amount of what is now left:\nx * 1-(1-x) or\nx (1-1+x) or \nx-x+x^2    or\nx^2\n\nif you add up what these 3 people had you get:\nx+(x-x^2)+x^2\nx+x-x^2+x^2\n2x\n\n1-2x=2x\n1-2x-2x=0\n1-4x=0\n-4x=-1\n4x=1\nx=1/4  or  .25

x = 4\ny = 9\n\nx^(1/2) + y = 11.... 1\ny^(1/2) + x = 7..... 2\n...\n1... 4^(1/2) + 9 = 2 + 9 = 11\n2... 9^(1/2) + 4 = 3 + 4 = 7 \n\n\nI will finish the working out later...
