There absence of a few subreddits here in lemmy world are making my experience somewhat incomplete. I was really into r/noiserock on reddit and would like to help re-create that community. It does not seem as straight forward though. Am I only allowed to create communities on my instance? I guess, in general, how are new...
Ron Swanson meme where he says “I’m a simple man”. He’s looking at the camera, in a brown suit, with a sexy mustache and very slight smirk. Background is blurry paintings. Caption says “I’m a simple man” at the top and “I see a reply, I upvote it” at the bottom. End description.
My room thermometer is consuming a full stack 3 AAA batteries in just 24 hours. I opened it and found that maybe the component circled in green is burnt (CAZB)....
I am sorry if this has been asked before, but when or will it be open sourced. It is the best Lemmy Client i have used yet but i dont like anything being closed source and i read somewhere the dev wants to open source it at some point. Just interested if there is an estimate.
Tanya Kamal Darwish, CEO of Rasan Organization, told Human Rights Watch that the purported reason for closing the group down was not because of its activities, but because the judge took issue with its logo, which contains the colors of the rainbow. The court order states that “the expert committee confirmed that the logo of...
Hi! I wanted to start to hoard my favorite tracks in the best possible quality. A lot of stuff is available through Deezer or Tidal i know, but what sources are you guys using when FLACs for particular albums or songs cannot be found on Deezer or Tidal? I wanted to get the Rock n Roll Train song from ACDC in FLAC, but Tidal...
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
I lost my electric fence tester, probably the pigs ate it. But I opened it once to resolder the earth wire and found it’s really just a voltage divider with resistors and leds, so I can probably rebuild with stuff I have. What resistor values though? 2k to 10k V run through the fence. If any of you good people have a diagram,...
