1) x spent on rest, x + 600 on food, x+x+600 = total spent\ntotal salary = 5/3 * spent = 5/3*(x+x+600)\n\n5/8*(x+x+600) = x+600\n375-600 = -1/4(x)\n900 = x (on rest)\n1500 (on food)\nspent total of 2400\ntotal salary = 4000\nsaved = 2/5 of total = 1600\n\n2) if it took 20 minutes (from 10:15 to 10:35) to change 50 degrees (20*2.5 = 50)\nand it took 30 minutes to change back 37.5 degrees (50-12.5=37.5) \n\nThen, the rate of cooling is 37.5 degrees/30 minutes = 1.25 degrees / minute of cooling\n\nTherefore, it took ten minutes of cooling to change 12.5 degrees, which means the time at which it was 12.5 degrees hotter than 11:05 was 10:55 pm.\n\nP.S. you have one tough teacher!  glad to see that you are getting a good education, cause these are not easy questions.

Well, not being online while doing your homework is usually a good start.  I don't know what the "math source book method" is, but what I recommend is start earlier, and remove distractions (i.e. don't do your homework sitting in front of the TV or computer).\n\nOh yeah, and quite complaining - I was up doing homework till 5:30 in the morning on Thursday night, and past 4 every night for about four nights straight.

Regroup and add.  You got the 5n, so you should be able to get the other part!\n\nn + n - 1 + n - 2 + n + 7 + n - 11 = \nn + n + n + n + n - 1 - 2 + 7 - 11 =\n5n - 7\n\nNotice that -1 -2 - 11 = -14, add 7 to it and you get -7\n\nNRT

simply subtract 7 from both sides. This leave you with\n\nx<_3

Advice:  If you're having trouble with homework, ask your teacher, look in your book, or even come here and ask for a push in the right direction.\nDo NOT just post your homework question with no explanation, and expect someone to give you the answer.  That, my friend, is cheating.

I'm an 8Th grade, and i spend about three hours more or less on my homework each night. but i am also in geometry, and high school chem. so i don't know how that effects the answer. the load is not bad though.

Get together with your friends and work on your homework together. A lot of times one of your friends may be able to explain it better than the teacher. Misery loves company !and that way you and your friends can spend the time together and fuss about the things you don't like about math.Just make sure that you do get the math done.

8 over 10 = 5 over x \nyes you cross multiply. you multiply 8 by x and 10 by 5\nso you get 8x = 50 = divide 50 by 8 and you get x = 50 over 8 = reduced into 25 over 4\nyou basically do the same thing for all those problems..just cross multiply\nyour school should have an afterschool tutor, attend those and catch up on what you've missed\ni sleep in class too =) but learn to pick the classes you sleep in lol, for example, i sleep in compsci class cuz seriuosly? who needs to know that...not liek ima be a graphics person or anyting like that.

Yea, i see where ur commin from. im 16 and a sophmore in high school but 7 hours of school is not really that much time in class cuz u gotta look at it as u gotta take out ur lunch that a half hour usually. then there is all the passing time for changing classes...thats about an half hour or more. so ur only in classes 6hrs right there that is only 1/4 of the day. besides the homework is to refresh your memory on what u learned in class that way u can learn something new next class. and 182 school days out of 365..thats not that many. i used to wonder the same thing and i used to think it was torture but its honestly not. ITS TO HELP YOU!!

You need to clarify your question on what subjects you need to work on and what time zone you are in and what type of homework and how much work is already written...\nI think if you are on the computer asking for answers, you are losing time away from that very subject...

For one day of homework you want to do hours of research?? Jeez! Just call a friend to work with tonight or be honest with the teacher and do it a day late. Or get to school early and use your own book. Is this a serious question?

Please! don't ask someone to do your homework for you. Ask your teacher for help if you are having trouble. Trust me, you WILL regret it if you try to get someone to do it for you.

What you want to do is progress till the x is the only thing on one side of the equation; so\n\nget the 7 on the other side by adding 7 to each side of the equation:\n3x-7+7=26+7; this comes out to \n3x=33\n\nstill with me?   you have to do the same thing to both sides of the equation to keep it equal, so since you had to add seven to get rid of minus seven, you also have to add seven to the other side.\n\nnow you have  3x=33 and you need to get rid of the 3 multiplier, so now you will divide each side of the equation by 3:\n3x /3=33/3, or\nx=11\n\nto check for accuracy, just plug your answer, 11, back into the original equation and make sure it works:\n3times11  -7= 26.    \n\nsee? it's not so hard when you take it step by step.  in a little while you'll be solving these in your head.\n\nblessings!\ncryllie
