math problem-help me solve?

Let's take it one part at a time.\n\nIf he worked 40 hours, and he gets $5 per hour, then he received 40X5= $200 dollars for those 40 hours.\n\nFOr overtime, he is paid 1 1/2 times his regular pay. How much is that? We just multiply 5 by 1 1/2 and we get $7.5. If he worked 5 hours for $7.5 an hour, then he received 5X7.5= $37.5 for those 5 hours.\n\nIn total, he earned $237.50.

D\n\nEither is sufficient.  \n1) will lead to 2 equations,2 unknowns which yield a unique solution for x and y:  x=y+1, x+y=77, therefore x=39, y=38.  xy=1482 \n\n2) If the sum is 77 and x and y have the same tens digit, then there are two solutions for {x,y}, namely {38,39} and {39,38}, however the product xy is the same. xy=1482

The objective of this problem is to "solve for t" which means to isolate it on one side of the equation, hoping that only a number appears on the other side.\n\nBegin by distributing the (-6) factor through the left-hand side's other group of terms:\n\n-24 + 6t = 12t\n\n... being careful to let the two minus signs "cancel each other out" and become a + sign.\n\nNow, we hope to "collect like terms" -- that is, terms containing 't' -- on the right side.  Do so by subtracting 6t from both sides:\n\n-24 = 6t\n\nNow, finally, divide by the "coefficient of t" which is 6:\n\n-4 = t\n\nAnd there is your solution!\n\nMany teachers instruct you to "check your work" by substituting the "answer" back into the original problem, to make sure it is correct.  Let's do that here:\n\n(-6)(4-(-4) = 12(-4)?\n\nSimplify the left-hand slightly:\n\n-6 * (8) = -48?\n-48 = -48\n\nYes!  This yielded a true mathematical statement, hence our solution of t=-4 was correct all along.\n\nHope this helps!

Add them together and divide by 5.\n\nWow. I could seriously have you people do my homework for me. Every night. I'll type out the problems and see how you all do. :P JP

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!
