Hi, can you help me with a math problem kbin? It's algebra, and it's been a long time since I've had to do it. Can you explain to me how simplifying the terms comes out to 9/2 in the pictured equation please?
Hey, I can take a swing at this. It’s basically just a question of understanding how fractions work (which is fumbled horrendously by teachers, at least where I’m from - I basically had to teach myself fractions all over again when I went back to school).
So, if you look at the terms on the left hand side, we have “x”, which is the same as saying “1x”, so the whole number “1”, we have a whole number “3” as part of “3x”, and we have the fraction that’s going to cause us to do a little work, “1/2” as part of “1/2x”.
Now, a whole number can be rewritten as a fraction, and this makes the most sense when you see fractions as little division problems unto themselves. For instance, the “1/2” could be read as “1 divided by 2”, or “0.5”. A whole number like “1”, then, could be rewritten as “1/1”, or “2/2”, or “3/3”, and so on.
Now, in order to add fractions together (which is what we’re trying to do since our ultimate goal is to get the variable that we’re solving for alone on one side of the equation), we need the denominator to be the same for all of our terms, i.e. the “common denominator”. Because we already know the denominator we likely need, the “2” in “1/2”, we simply need to transform both of our whole numbers into fractions with 2 in the denominator.
For “1”, this can be rewritten as “2/2”. Dividing 2 by 2 gets us back to 1, so that works out.
For “3”, we need to determine what number divided by 2 gets us to 3. In this case, that’s 6, which leaves us with “6/2”.
The equation now looks like this: 2/2x + 6/2x + 1/2x = 45
We can, of course, pull the “x” out like this: x(2/2 + 6/2 + 1/2) = 45
Then, when adding fractions, we only add the numerators (the reason we were looking for the common denominator in the first place). So, 2 + 6 + 1 = 9, leaving us with “9/2x = 45”. It’s then just a question, as you can see in the posted solution, of multiplying both sides by the reciprocal to solve for x.
@nyarlathotep thank you so much! There's other comments to read below, but this is the first one that has triggered my memory for common denominators. You've explained it brilliantly!
Edit: can you explain how the reciprocal works and comes out to 2/9? Been a long time since high school
Cybersecurity employee training that includes chatbots? I know, I know. I should ask this in technology or something but what im really looking for is more business related. Im looking for those duh, duh, kind of employee training but updated with the dangers of chatbots. Things like don't paste in private or confidential data, don't trust its answers are right, ask questions generally and move down to specifics, etc. etc. And yes I did ask a chatbot for the answer.
Is it possible to stop the screen from rotating on the Kbin app when my phone rotates? I have my phone settings so it shouldn't rotate from vertical to horizontal but for some reason only the app does it, anyone know if this can be turned off?
I have a set of Bose QuietComfort earbuds I wear daily for workouts. I finally killed them and in the market for something new. I'm looking for higher end name-brand earbuds which would work for my exercising needs (bicycle rides, and gym workouts). ANC is necessary (but pretty common on all the top brands/TWS earbuds these days).
I was thinking about the Bose QC2 as it would be the logical upgrade, but I've heard mix reviews about them and I can't figure out if it was just a bad batch of earbuds or if it's a poorly designed product.
I guess the Sony XM4's would be a logical alternative but I don't know how comfortable they are for exercising
Edit - Android user, so apple airpods aren't an ideal option
What are some tips for dealing with solicitors (door-to-door salespeople)? Our neighborhood gets a lot of them.
We have a “No solicitors” sign hanging on the front door. Nevertheless, they knock, ring the doorbell, or worse, yell through the front window when it is open, trying to get our attention.
We have a Ring video doorbell and have enabled the automatic “Sorry, we’re not interested” announcement after 15 seconds. These pushy SOBs ignore the sign and the announcement.
When I ultimately find out they are soliciting and I ask why they ignored both the sign and the doorbell announcement, they usually say something like, “I’m not selling anything. I am just working with some people in the neighborhood…” or some such BS.
My wife and I work from home and have had to explain the window shouting to coworkers in meetings. We also have two small children who could be trying to nap at any given time. We have good reasons to not want to be disturbed at home and these assholes disregard that wish.
I will write a negative review online if I find out their name and company they are representing. Any other ways to get these people to leave us alone?
why do threads that reference articles on outside sites redirect to kbin and not the outside site? (for example, worldnews often shows the external news site, but clicking the link takes you to a kbin.social post showing all the threads referencing that news site, not the actual site and story itself)
Hot sleepers, have you had any real world success with cooling blankets that give you that good weighted-down feeling but don’t reduce you to a sweaty blob by morning?
@ike according to ernest it stems from /sbin. though one of the early instances was named karabin based on the karabine gun and thus shortened to kbin (or rather expanded from kbin).
Why is my phone screen's orientation failing to stay locked and how do I fix it?
I have a Samsung Galaxy A71 5G. This usually only happens a few times a week, but my phone seems to be very confused by kbin. I have to hold it vertically or it will switch to landscape orientation every single time. It's annoying. Any ideas?
@HotDogFingies on kbin specifically (if you're using the progressive web app PWA) it currently bypasses your phones landscape or portrait lock. Even on my phone with Android 13, if I've switched off auto rotation and rotate the site it still rotates
That's apparently a bug that's going to be fixed at some point.
