leave r on one side by subtracting 5/3 r to the left side. r = (5/3)r + (20/3) -(5/3)r + r = 20/3 (-2/3)r = 20/3 solving for r: (20/3) / (-2/3) = -10 Answer: r = -10

I'm using in-line citations. A few of my sources have no author. When I write them, should I quote the title (they're articles)? Thanks.

I need your opinion on this. I'm writing a research paper with fairly long paragraphs. My teacher said we only need to cite once a paragraph if it is all from the same source, but I feel like that's not enough. Should I cite every line? (My essay is going on turn it in...

***Latin Urgent***
As I'm studying these prepositions to be used in the ablative case, I had a question. How do you know when to use a (with a macron) verus ab? What about e (with a macron) versus ex? Thanks for your explantion!

Latin
If you're using the vocative case for a plural word like friends pluralized, would it be amici or amicis, or something different? Thanks!

Latin
That was it exactly. Thanks for answering my question.

Latin
When you're conjugating an -ere verb, such as docere, when do you put the macron on the past tense forms? I know in present tense, the macron is only used for you singular+plural and we. Are -ere verbs inconsistent like this, or is it consistent like the future tense? ...

I'm still a little unsure in front of the first Al why there's a two. Could you explain?

Chemistry
My teacher says the correct way to predict/balance the equation AL+HCL yields H+AlCl3 is to balance it like this: 2Al+6HCl yields 3H2+2AlCl3. I don't get why there is a two in front of the AlCl3. Could you guide me through the logic of this please?

Yeah I wasn't sure if it'd be quite right...I do have some other suggestions though. I always pictured him as a sort of Captain Cook from Peter Pan, or maybe Lord Voldemort that'd be creepy...or the giant from Jack and the Beanstalk.
