Let's help you learn how not to suck at math. \nFirst step, is to figure out exactly what they are asking for. In this case, it will be the weight of the bread she has left. \nTaking it in steps:\nIf Molly has 1/5 of a loaf of bread, and a full loaf weighs 5 lbs, how many pounds of bread does she have to begin with? \nIf she eats half of it, divide that number by 2, and you have your answer. \nOkay?\n\nThis question must have been put together by a guy. A five pound loaf of bread would be stupendous!

okay.  here's the formula to solving this problem.  heat=mass*calories*change in temperature.\n\n1)5 grams\n2) the change in temperature is 100 degrees\n3)1 calorie per gram\n\nso the answer is 5*100*1=500

Say he ate x cookies on the first day. Then he ate x+6 on the second day and x+12 on the third day, etc..\nso:\n\nx+(x+6)+(x+12)+(x+18)+(x+24)= 100\n5x+60=100\n5x=40\nx=8\n\nso he ate 8 on the first day.

2 = 2000 * 5\n\n2 = 10000\n\n2/2 = 10000/2\n\n1 = 5000

yes, I can.\n\nAnd so can you.\n\nWhat this problem says to me is that when she left store two, she had 1/4 of the money she had left after leaving store one which was $20.\nThat would mean that she had 4 times that much after she left store one.\nThat means she had $80 after leaving store one.\nThat means that 5/8 of her whole amount of money was $80 (because that was what she had left after spending 3/8 of it).\nSo that means that 1/8th of her whole amount of money was $16 (found by dividing 80/5).\n\nThat means 8/8 of her whole amount of money is $128 (found by multiplying $16 by 8).\n\nThat means she started out with $128...\n\nNow, show your work when you turn it in. \n\nOh, you still have to turn my answer into math terms. Good Luck.\n\nTo prove your answer work it backwards.\n\nAssume she started with $128.\nSpend 3/8 of it at store one. That means she has 5/8 left, so she has $128/8 then X 5 = $80 left.\nThen Spend 3/4 of the $80. That means she has 1/4 left. So 1/4 of $80 equals $80/4 which of course is....    $20\n\nOnce again the integrity of mathematics has been preserved.

31 / 5\n\nThat's because .2 is 1 / 5, so I just converted the 6 to 30 / 5 and added one more.

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

The waitress calculation is wrong...\n\nYou me and Sally gave the waitress $10 each for a total of $30.\n\nThe waitress gave back $5\n\nWe gave the waitress back $2.\n\nTherefore, the waitress has $30 - $5 + $2 = $27

What math test do you take?  I'm in Algebra 1 and I only remember 1 question.  It's impossible.\n\nSomeone has a total of 100 coins in dimes and quarters.  The total value adds up to $14.05. How many quarters does she have?\n\nA) 27 (I chose this-it's a dollar off)\nB) 40\nC) 56\nD) 79 (I forget-it's way too high)\n\nWell, that's all I have.  Bye bye!\n\nThanks to the guy who solved that.  I won't get a zero now!

Give her a break. Everyone is here coz they didn't really listen in class or need help. That's why we are here to answer them.\n\n1) 11% (275/2500 x 100 = Answer)\n\n2) 963 (900/100 x 107 = Answer)\n\n3) 750 s (300/40 x 100 = Answer)\n\n4) 7550 (8882/100 x 85 = Answer)\n\n5) $20442.50 (18500/10 x 110.5 = Answer)\n\n6) $5875.20 (6400/100 x 8.2 = Answer) \n\nI've done it for u, u better buck up in ur maths. These are the basics.

let us say that she is walking in the x direction (positive) \n\nThis is a question of momentum... \np = mv   \n(momentum equals mass times velocity)\n\nand we have the conservation of momentum \np_1  +p_2 = p_(total)\nThe sum of the momentums is equal to the total momentum of the system\n\nSo in the begining she is not moving... so the total momentum of the system is zero... it will always be zero.  \n\nShe walks... her momentum is p_1 = 45*1.5 = 67.5 kg*m/s\n\nand we know that p_1 + p_2 = 0\n\nso \np_1 = -p_2 \nor \n67.5 = - m v = - 150 *v\nso the velocity of the plank is -0.45 m/s.  \n\nNow we just sum the velocities to get the total velocity and we see that she is traveling at 1.05 m/s relitive to the ice. \n\nGood question ... i have not thought about a problem like this in a long time
