arrived guests = a
invited guests = i
\frac{2}{3}i = a
arrived guests = a
invited guests = i
\frac{2}{3}i = a
yes.
Seven more invited guests arrived including Cedric. Now 5/6 of the invited guests are present.
Can you make the equation for this?
\frac{5}{6}i= a+7
Yes. Does doing the problem that way make sense? Do you see how those equations and variables correspond to the words more directly and better explain whatās going on?
Yeah, I do. I just had a hard time, initially, seeing the guests that had already arrived there as a variable. My mind was only seeing the invited guests as the variable there.
For #3, what was your final answer?
For #2, can you try setting it up using two equations?
For the problem I did x_1 = w , x_2=x , x_3 = y , x_4=z . It made a lot easier to look at for me.
I did a four variable system of linear equations. It took me ~1hr 30 minutes. I got it right. A lot of time was spent on calculations. Almost everything was calculated by hand. I only stopped calculating by hand right at the end. When I finally solved for y and got a fraction. I knew that from the answers that the website usually looks for I was (probably) wrong.
I looked through my work and my only error (that I know of) was on page 3 and 4. The equation numbered 7. The equation was equal to 2821. I accidentally, one line down, wrote it as equal to 2827. This frustrated me. The frustration plus being tired made me just do the rest with the calculator.
Hereās my work:
Itās good that your understanding of the concepts worked for this. I donāt think practicing it is needed.
#2
c-1/2c = s
4/5s = r
Hmm. I donāt think that helps. Trying to set it up as two is confusing.
Kk. So is my understanding of solving linear equations by substitution fine?
yes
oops i mixed up the numbers and meant to ask about #2 there
4/5s = 1/2c
Youāre putting the variables in the denominator. i think you meant 4s/5 and c/2. Using parenthesis would work too but is unnecessary. Do you understand the issue?
hmm that would 4/5s = s. That makes no sense.
Youāre trying to judge the equations by calculating, and maybe trying to write down things in the format you expect to calculate based on instead of just writing down what the problem says. Itās important to be able to judge whether or not they match what the problem says, which doesnāt require calculating to see if they give a good answer.
I should have said 2+ equations not 2. In general, use as many equations and variables as you need. Go through each thing the problem says and try to model it in a clear, understandable way.
oops i mixed up the numbers and meant to ask about #2 there
Kk. I got 1c/10 as my answer. I now remember that when I did #2 initially I was going to note down that my process didnāt follow the steps well. I think I was tired when I did these so I just posted what I did and forgot to mention that.

Yes. Huh, now that you pointed that out I canāt read them as I intended anymore, neat. Thank you.
Coins given by emmaās parents = c
She lost half her coins on the way to school
s = what she lost on the way to school
c - c/2 = s
she found four-fifths of the coins she had lost
coins she found = f
4s/5 = f
Hmm. I think those are better? Iām confused as to how I would put down how many coins she was still missing. I know it would be the coins she didnāt lose plus the coins she found subtracted from the initial amount of coins, but I donāt think I can do that right from the problem.

ending_coins = starting_coins - lost_coins + found_coins
does that make sense and let you continue on the problem? you had the variables needed to represent this. i just renamed them for clarity. Iām not sure why you used āsā btw. I would have picked ālā for lost if using one letter.
you had the variables needed to represent this.
I think I may be confusing myself on the way I should be approaching these problems. I know I had starting coins, lost coins and found coins. However, since nowhere in the problem stated that ending coins is equal to starting coins - lost coins + found coins I thought I couldnāt make an equation for it.
Iām not sure why you used āsā btw.
Coins lost on the way to school. school. school = s :), probably not the best to represent it now that I think about it. I think my brain just auto assigned it and I think I subconsciously assumed there would be more places where we lost coins to assign.

You often have to think about what the words mean (some but not too much ā understanding the words isnāt meant to be very complicated with these). They sometimes assume some simple background knowledge.
The actual thing the problem asks about is ending_missing_coins_fraction not ending_coins though. So you could make an equation for that and finish the problem.
Assignment: Write 15+ minutes per day. Subject matter is up to you. I just want to get you more comfortable with writing.
You can do private journaling, you can write thoughts on intellectual issues, you can write todo lists to organize your days, you can write commentary on TV and YouTube, you can write suggestions for your workplace (no need to tell your workplace), you can write notes on things you learned, you can write explanations of how to do things, whatever.
Try not to skip more than 1 or 2 days per week. Keep track of what days you write on and maybe time and word count. But donāt try to make your time or word count go up; big numbers arenāt the goal here.
Share a write every week or two. Itās fine if most of it is private but try to write something shareable sometimes. You can share more if you want to.

coins sheās still missing (m) = coins she started with (c) - coins she ends with (e)
m = c - e
Ok good try a couple more word problems

Ok. I used to do this. I would never say it was ever a really consistent habit but Iād primarily just write down any thoughts that came to mind. Some weeks Iād write daily for two weeks straight, other times I wouldnāt write at all for a week. The earliest log I have in my notes app of me doing this is from February 2020. Prior to using note-taking apps I would log down ideas into a small moleskin notebook I had at the time. I think I filled it up 3/4 of the way from 2018-2020? I transcribed the stuff in there to my notes app.

Just noting down the kind of writing I already do:

Hmm. Looking at my notes app I just realized how bad Iāve actually been with writing as of recent. I think Iāll brainstorm as to possible reasons today and share it. Iāve never been consistent but this is the least amount of stuff Iāve written in the past ~6 years.
To get the ball rolling I guess hereās something Iāve written down before that I donāt mind sharing:
August 18th, 2020
- Art is not the primary cause, ideas are. Donāt blame trashy and ghetto rap, donāt blame post-modern art, donāt blame nihilistic movies for our problems. These are merely the consequences of ideas. [[General Notes and Thoughts]]
- I would say 99.9% of the time regulators arenāt actually genuinely surprised that no one reads their absurd 1,000,000 page regulation. The point of the regulation is that it is 1,000,000 pages. They expect people not to be able to read all of it, they expect people not to be able to comply with all of it. Having too many laws is just as unbearable as having vague laws, for they fit the same purpose. [[Law]] [[General Notes and Thoughts]]
- Death is merely an effect, to kill someone is a secondary cause, the motive is the primary cause. The cause determines the crime. This is a perfect example of the means determine the ends, that cause determines the overall effect. It is the means and cause by which someone is killed that determines if it was a murder or a self-defense.
- To kill someone does not exist, to murder someone, does. To kill someone does not exist, self-defense, does. What each of those definitions take into account is context. It is context that determines the action. There is no such thing as pure killing, that is an abstraction detached from reality. Killing has causes, i.e. context, to give its true nature. [[General Notes and Thoughts]] [[Law]]
itās not recent and I donāt intend to dump old stuff Iāve written here but Iāve been organizing my notes app recently and liked this. I donāt know if I still agree with it all, especially the the last two. This makes me wonder: do you want me to explain why and what exactly Iām sharing with you when I do share?
I just copied and pasted this from my note-taking app. Itās 888 words. I wrote for about ~30 minutes. I used my own quote below as a prompt.
