I hope I am not keeping u from doing other stuff. You sure have helped with my math.

#327 Re: Help Me ! » Standard normal curve » 2011-04-19 16:59:28

did u learn this in school or was it inherited?

#328 Re: Help Me ! » Standard normal curve » 2011-04-19 16:51:58

i am going to try to work a decimal one.
0.30 (6) + 0.05x = 0.15 (6+x)

#329 Re: Help Me ! » Standard normal curve » 2011-04-19 16:48:30

hey I just one right. haha funny

#330 Re: Help Me ! » Standard normal curve » 2011-04-19 16:37:06

Let's see. Here's one with decimals. 0.04(y + 9000) = 1440.  They want a solution set.
I can stay up about another forty minutes. Then I can get enough sleep hopefully. I hope tomorrow is not a repeat of Monday.

#331 Re: Help Me ! » Standard normal curve » 2011-04-19 16:33:45

You are exactly right. I had typed in 42/12, which was wrong, yours was right.:)

#332 Re: Help Me ! » Standard normal curve » 2011-04-19 16:32:21

let me see if it takes. I was thinking the answer had to be denominator of 42. be right back.

#333 Re: Help Me ! » Standard normal curve » 2011-04-19 15:55:05

Yes this one is written correctly. They just want solution set.

#334 Re: Help Me ! » Standard normal curve » 2011-04-19 15:53:04

No, they want the solution set from that one. smile And thank you.

#335 Re: Help Me ! » Standard normal curve » 2011-04-19 15:16:37

denominator is 42,  so subtract 42 from both sides can't be done.
0.30 (6) + 0.05x = 0.15 (6 +x) I have about 30 more of these to go for now.

I also have  test on powerpoint tomorrow, wish me luck.

#336 Re: Help Me ! » Standard normal curve » 2011-04-19 14:56:30

5x            3x
___   _     __  = 1 Find the solution set. I thought it had a 12 denominator, but it did not.

6              7   
I did get one right while you were gone. I don't know how though.

thanks, i will be here working on algebra.

#338 Re: Help Me ! » Standard normal curve » 2011-04-19 13:54:27

yes i think so. Yesterday morning was Monday and i had to drive about 30 min. to class. I was so tired even after sleep. The brain does control and if fear is in there...well you know.
I am 100% on all my homework thus far, and this is my last four groupings of homework. All Algebra now.
I saw most of the Star Wars movies, some of them twice. Especially the first ones. I remember them. Yoda was the teacher.
So I guess you can teach me, someone needs to.

#339 Re: Help Me ! » Standard normal curve » 2011-04-19 13:35:54

This is all true, but my homework is still due in a couple of days.
Yes, I have always feared math and that is why I put it all at the last. I should have spaced it out and thrown away the fear. Fear controls everything.
I forgot to ask what the answer to the problem is. It is not -70, according to the computer world of math classes.

#340 Re: Help Me ! » Standard normal curve » 2011-04-19 13:00:04

i have often heard other students who cannot do much with English or write a paper and are geniuses in math. One of my past teachers said he took algebra three times before he passed it.
This has been traumatic for me when this is the first time i will not be on the honors list or the Deans list for sure because of 3 math classes at one time, and the research class might get an a. I can write anything.
People are different and you are a genius in math.

#341 Re: Help Me ! » Standard normal curve » 2011-04-19 12:57:02

I am a silly student in math. I hope I make it the next 3 weeks.

#346 Re: Help Me ! » Standard normal curve » 2011-04-19 12:32:24

Do u subtract it from the other side 28?

#347 Re: Help Me ! » Standard normal curve » 2011-04-19 12:21:01

0
I am sorry to keep you waiting so long. I had to fill out something for college in the fall.

#348 Re: Help Me ! » Standard normal curve » 2011-04-19 11:55:48

well, we have already subtracted 14
