A * [(B + C)(D - E) - F(G*H) ] / J = 10
Knowing that each variable is a unique, single-digit, nonzero number, and that C - B = 1, and H - G = 3, what is the number ABCDEFGHJ, where each letter is a digit? For example, if A = 4, B = 2, and C = 7, ABC would equal 427.
Anyone know the answer? Math is my worst subject and I need help!! :P
Math Question For Neopets?
There are precisely three answers:
ABCDEFGHJ
267835149
267953148
678413259
(slightly offtopic, how can you spend 30 minutes on a question that was asked 8 minutes before you answered ;) Just kidding.)
Try each one and check that it works :) Unless you didn't mean F(G*H) as F*(G*H), and meant the digit F followed by the answer G*H.. in which case I'll try solving it again. If you did mean it like that, there is indeed a unique answer:
589736142
Ahha, third question change. Now it becomes 256973148.
Reply:I know, right? I spent about 30 minutes trying to solve it! I got nothing. I would be glad to help, but, unfortunately can't. Sorry!
Reply:This is the third time that this question has been asked!?!?!
It's a tough one, too.
I'm taking it to work with me and asking my colleges to help me out on it.
But someone "did" crack this CHALLENGE Question.
So here's the answer. . .
http://answers.yahoo.com/question/index;...
ANSWER: ABCDEFGHJ = 25,693,148
A=2
B=5
C=6
D=9
E=7
F=3
G=1
H=4
J=8

Does a C- in high school equal a C in college?
I can get out of having to take a math class in college if I had a C in high school geometry, and I had a C-.
Will that be enough?
Does a C- in high school equal a C in college?
Why would a C- in a high school course possible equal a C in college? College can't be easier than high school.
I highly doubt you'll be excused from taking it, unless you bring it up.
Reply:A C- is a below average grade-
In college they do grade on a 3-5% higher score than in high school. I would not be suprised if you have to take the college class, because it doesn't look like you have a great handle on the basics of geometry.
Reply:an A in highschool is like a low A in college a C- in highschool is like a D in college because they go on a different GPA scoring highschool goes on a basic 3.0 GPA you might get over a 3.0 GPA but its what you earned divided by the possible then blah blah etc etc anyway no you would most likely have to take the class in college,
Reply:College usually expects more out of its students than high school does. The college professor may require that you show all of your work a certain way. Most of the time grading in college is a lot tougher.
Reply:A C- is less than a C./ It probably will not be accepted. You should ask the college directly for the most accurate answer.

If my math grades were not excellent in high school, can I make up for them in college?
I would like to become a pediatrician. In high school my math grades were pretty average (b's and one c) and I had a really low SAT score of 480, but since then I got a math tutor and have B's and A's. (I'm now a Freshman in college). Although I didn't really have a great background in mathematics, I am extremely passionate about all of the Sciences and I got all A's, even Chemistry and Physics which seem like second math courses. Will the fact that I was not really strong in math impact my ability to get in to Med. School?
I know that this career path is extremely demanding and I am willing to do whatever it takes.

Your ability to get into med. school depends on four things: MCAT score, overall GPA, performance in particular classes in college, and the amount of volunteer experience you have in the medical field. I think most pre-med programs (my school doesn't have the major, but instead an advising office) advise doing a year of calculus, a year of organic chemistry, a year of inorganic chemistry, a year of physics and a year of biology. In theory, as long as you take those classes (doesn't matter what major you are) and perform well, get a great MCAT score, maintain at least a 3.6 GPA, and do lots of volunteer and community service work in some sort of medical field, you will get accepted to some fantastic programs. Good luck - I'll be starting my senior year in the fall as a History/German double major and I'm contemplating staying an additional year to do the pre-med requirements and completely change my path. We'll see.
Reply:You just have to work on your mathematical skills- at a higher level. Now that you're in College, more is going to be expected of you! Whether you know the material or not. Just study hard, and keep your head in the books. High School courses are highly different from College courses. So, since you're a freshman, you NOW have a chance to start over. Just make the most of it, and keep getting those A's and B's.
Good Luck to ya
Reply:Nobody cares about highschool.. It doesn't matter at all.
They will look at college grades, MCAT score, and what you have done outside of school..
Reply:Yes you can! In fact most colleges prefer you take an aptitude skills test in math and if necessary, a 100 level math class. The great thing about it is that whether you choose to take Basic Finite Math (addition, subtraction, multiplication, division), Basic Algebra, or Basic Geometry, you will typically improve over your high school level classes based on the subject material, individual (free) tutor assistants and, typically, student academic enrichment programs - geared toward bringing you up to college level fast!
Reply:I sucked at math in High School and hated it with a passion. When I went to college (20-some years later), I had all A's in all my math classes and even thought about changing my major to math. So yes, you can. I guess that teh important thing is to challenege yourself and to keep at it. I found that math of all things is lost quickly when one doesn't use it constantly.
Reply:WHAT YOU DO IN HIGH SCHOOL IS WHAT YOU DO IN HIGH SCHOOL!! IT STAYS THERE. YOU CAN'T JUST TAKE YOUR GRADES FROM COLLEGE TO HIGH SCHOOL!!! YOU CAN IMPROVE YOUR GRADES AND CHANGE COLLEGES.
Reply:"I know that this career path is extremely demanding and I am willing to do whatever it takes."
The Past cannot be erased , The future cannot be predicted, But the present is a present that is written and acted upon today.
Math is practise and practise makes perfect, so if you are willing and an effort is there so will be success.
School is just a phase of general education and college opens up doors.

Cost function math problem?
How did they get problem 2 a) c) e)

Cost function math problem?
a) since it says the relationship of cost to number produced is linear, you are solving for the equation of a line. They give you two points:
(100, 2200) and (300, 4800). Now use whatever method you want to get the equation. Personally I almost always use y=mx+b.
m = (4800-2200) / (300-100) = 13
y=13x+b
Now plug in one of the points for x and y and solve for b:
2200 = 13(100) + b
2200=1300+b
900 = b
y = 13x + 900
c) The y intercept is the value of y when x = 0. So take the equation and plug in x=0:
y = 13(0) + 900 = 900.
e) You were right on this one... P(q) = R(q) - C(q). You just need to plug in the R(q) from part (d) and the C(q) from part (a)...
P(q) = 17.5q - (13q + 900)
Best of luck!

I ant to go uni but i only have 4 A-C's(including eng and maths) and a couple of D's what more do i need to do
at what level have you got these results? GCSE or A Level? what do you want to study at Uni, and where? Answering those questions would help people help you
I ant to go uni but i only have 4 A-C's(including eng and maths) and a couple of D's what more do i need to do
I assume these are your GCSE results - these are good enough to get you into a 6th form/FE college where you should do A levels, and it is the A levels that universities will look at first when considering your application - GCSEs are a secondary concern.
If you are a mature student (over 21) you should a one-year 'Access to Higher Eduation' course at your local FE college. this will prepare you for study and can be tailored towards whatever subject you want to do at uni.
Most uni's will accept you as long as you pass the access course.
Reply:Well for a start I would spend more time checking your work before submitting it and stop using abbreviations!
Reply:Well, if you don't get into a university on your grades from high school, perhaps you should start out at a community college. That way, you can improve your gpa to get into university.
Reply:are these gcse's or a levels? if they are gcse's then you will need a minimum of 5 gcse grades a-c in english and maths if these are a levels grades you will be fine :)
Reply:Hi, education is always a good thing to aspire to! Firstly, how old are you? If you are 21+ then the thing I would recommend would be a 1 year Access Course which is just mature students - there should be one at a college local to you. It is the same standard as A Levels and would prepare you for Uni really well. A Levels are an option as well, again at a college though Access courses are encouraged more. Also, depending on what you want to study, you may be able to get on by experience such as work background if, again, you are 21+. Whatever you choose, go for it - and find out as much as you can about the course you want to do beforehand
Reply:are these grades in GCSE or a level?, assuming they are gcse then I would suggest you go to college/school and do some a level courses or a National Diploma, the only way to can avoid doing these courses and going straight on to do a degee is by studying with the open university, im not sure how old you have to be though. Anyways with 4 a-c along with a levels, you will definately be able to get into quite a few universities, i didnt do much better than yourself but managed to get into Leeds Met University and was offered places in 2 or 3 other universities.....so you have nothing to worry about....good luck
