Question:(1) Working as waiter, Michael earns $6.50 per hour, plus tips. Last night he received$36.50 in tips and earned a total of $65.75. How many hours did he work? (2) Mr. Kork sold his car for$8,400. This was $200 more than two fifths of what he had paid for the car originally. How much had Mr. Kork paid for the car? Answers:(2) Mr. Kork sold his car for$8,400. This was $200 more than two fifths of what he had paid for the car originally. How much had Mr. Kork paid for the car? Let x = the amount he paid for his car then, (2/5)x + 200 = 8400 solve for x multiply through by 5 2x + 1000 = 42000 2x = 41000 x = 20500 He paid$20,500 for the car Check One problem at a time QED

Question:Please give me the answers to these problems and explain to me how you found the answers. Show your work. Simplify the espression: -2(-5 - 3) Solve for x: 1. x=(-4)*(-6 - 7) * = multiply sign 2. 6= -9 + 8x 3. x/7 - 5 =16 4. -24= 6 - 3x 5.6/x = 42

Answers:-2(-5 - 3)--> multiply the -2 with -5 and -3 = (-2*(-5)) - (-2*(-2)) = (10 - 4) = 6 1. x=(-4)*(-6 - 7) first do -6 - 7 x = (-4)*(-13) now multiply -4 with -13 x = 52, since both -4 and -13 are negative, the answer is positive 2. 6= -9 + 8x, first isolate the 8x by adding 9 on both side of the equation 6 + 9 = - 9 + 8x 15 = 8x, now isolate the x by dividing 8 by both side of the equation 15/8 = 8x/8 15/8 = x 3. x/7 - 5 =16, isolate the x/7 by adding both sides by 5 x/7 -5 +5 = 16 + 5 x/7 = 21, isolate the x by multiplying both side of the equation by 7 x/7 x 7 = 21 x 7 x = 21 x 7 x =147 4. -24= 6 - 3x, isolate the -3x by subtracting both side by 6 -24 - 6 = 6 - 6 - 3x -30 = -3x, isolate the x by dividing both sides by -3 -30/-3 = -3x/-3 10 = x 5.6/x = 42, isolate the x by multiplying both side by 1/6 6/x*1/6 = 42* 1/6, now the 6 in the 6/x can cancel out with 1/6 x = 42*1/6 x = 42/6 = 7

Question:How do I solve: n+5 ____ =-1 -16 Solve for n and how?

Answers:multiply both sides by -16 to get rid of the -16 on the left then -5. So its n+5 (-16)------- = -1 (-16) -16 N+5=16 -5 -5 n=11

Question:I need an algebra calculator that is free and shows you steps. I am looking at the answer key to this portion of questions I am doing and it doesn't show how they got the answer. Please? No pay sites please. I want to learn how to do the steps, that is why I am asking for them to be shown. I know myalgebra.com has a calculator but to show steps it takes a payment. Please don't tell me that I shouldn't use a calculator, I just want to use it on a couple equations so that I know that I am doing the steps correctly. Because as of right now, I have no idea what I am doing.
