Chap 2 Practice Packet Section 2-4 #16-19

Hi, on the email you sent, it says do page 137, but here it says 127, which page should I do?

ReplyDeleteRead the follow-up email with the correction?

DeleteWe did section 2-7 in class today... I'm confident you can figure it out.

I am experiencing some Brain Traffic on Question 17 and I'm writing this to make sure I don't screw it up, on Question 17 the Problem is Stated as "14+3n=8n-3(n-4)

ReplyDelete1"

I looked and saw it on another question but saw no operation sign or symbol anywhere, is the one a typo or does it mean something?

Dear Longest Name Ever,

DeleteJust Ignore the other numbers and do "14+3n = 8n -3(n-4)"

oops... looks like I gave you a copy of the answer key... oh well... I was going to email the answer key to you anyway... try to ignore the answers and do the problems... it's the PROCESS that counts... I will typically supply you with answers for most (almost all) of your homework problems.

DeleteI've got competition? Wow, I didn't think that anyone would notice/care how long my username was. This is hilarious XD

DeleteMr. C,

ReplyDeleteDo we put the POE's on this homework?

I am a big POE fan!!!

DeleteHello all,

ReplyDeleteI had a question about 16-19 on the practice packet. For the question do we solve for the variable or with the variable since the answer is right there.

-Trumposaurus Rex(Donate to my campaign so we can build a massive wall)

Pretend you don't know the answer and just solve. Your answer key is embedded in the packet.. woo-hoo... maybe I'll make the same mistake on the Chapter 2 Test???

DeleteNOT!!!

DeleteNo walls

DeleteJust... no

Unless you're a Trump fan, then I respect that

If you were saying it as a joke, then ok

Just tell me

Because that name triggers me

Ok... I'm rambling at this point, so bye...

That was odd.

DeleteI am confused on means and extremes. I watched the video on math chamber academy and I'm still confused!

ReplyDeleteDear Fuzzy,

DeleteThere is nothing to understand, really. It's just a pair of identifiers. In a two ratio proportion, the upper left numerator and the lower right denominator are called the EXTREMES and the the lower left denominator and the upper right numerator are called the MEANS. They are just names. Can I call you UN-Confuzzled now??

Hi Mr C, I have a question on number 3 of pg 127 in our books. The question is:w+3/4=w/2. Would you have a blob of w+3 and do the cpp of 4/1+w/2?

ReplyDeleteYou need to include parentheses in your question... as written, it doesn't make much sense. I think you need to watch the third of the three "2-7" videos. Have you watched that?

DeleteThanks mr C, the video helped a lot. The problem with the parens is this: (w+3)/4=w/2.

DeleteJust treat every proportion like (a)/(b) = (c)/(d) and follow CPP (i.e. ad = bc) and you will be just ducky.

DeleteMr. C for question 23 on page 127, 8/p = 3/10 for our answer can we just leave it as p=80/3 or do we have to put it as p=26 2/3(aka 26.6666666666666666666666666...)

ReplyDelete80/3 works for me. 26 2/3 is also fine... I am not a fan of 26.66 repeating. When a problem starts as a fractions, the answer should be left as a fraction (unless otherwise requested).

DeleteIn class we did a similar problem and Mr.C said you can just leave it as a fraction.

ReplyDeleteoh okay thx

ReplyDeleteDo you want x= as my answer or 90=5x

ReplyDeleteA proportion is simply a specific type of equation. Solving proportions is just like solving equations. You GOTSK to isolate the variable, i.e. "x= "...

DeleteCapeesh?

are the packet problems hand in????

ReplyDeleteI think so(i erased my other comment because it had a TYPO!!!(My only weakness!))

DeleteNo, just #24 & 36

DeleteWhere is the answer key for the packet?

ReplyDeleteI can't find it in my packet.

It's posted on the blog.

DeleteAnd YOU'RE the one stealing MY thunder.

You wanna go? Jk XD

I don't think there's an answer key (yet), but if he didn't post it yet, he probably won't post it.

ReplyDeleteHere is the problems though:

DeleteSolve each equation, check each answer:

16. -8x - (3x + 6) = 4 - x

17: 14 + 3n = 8n - 3(n - 4)

Determine whether each is an identity or whether it has no solution:

18: 4(3m + 4) = 2(6m + 8)

19. 5x + 2x - 3 = -3x + 10x

There are the problems, 2-4 16-19

(No problemo)

Also, what's with all these long names?? (that gives me an idea...)

DeletePeople, people. The answers are underneath each problem. There's no separate answer sheet.

Delete@The Procrastinator

DeleteWell, how else are we supposed to express ourselves? We wanna do that with our names, leave it at that XD

ReplyDeleteMr.C (or anybody else who knows the answer) i was solving for a variable using POE and I used the double earmuff method but I forgot the official name and I couldn't find it in my notes can you help me

ReplyDelete"Double earmuffs" is simply the Multiplication POE twice.

DeleteIt says #25&32!

ReplyDeleteMr Chamberlain,

ReplyDeleteWhen is the chapter 2 test?

in due time... I'm working on it.
