Thanks for the help, I really like the explanation for the first question. That is great. For the second question, why does the second premise not work? My guess is that it doesn't tell you anything about the sum. The second statement does tell us *something* about the sum, because to say that a nu...

Great work here, everyone! Here's what I think of as the major takeaway from this problem (and it's something everyone who solved it clearly already knows :)) -- I've seen students get tripped up by this and many other problems (in all math sub-topics) because they're trying to get to the answer DIR...

It would take one machine 4 hours to complete a large production order and another machine 3 hours to complete the same order. How many hours would it take both machines, working simultaneously at their respective constant rates, to complete the order? 1/A + 1/B = 1/T 1/4 + 1/3 = 1/T => 3/12 + 4/12...

Responding to a PM... Kevin's points are exactly right. Our "because..." phrase in (B) is TRYING to function as a noun, but it can't: "because..." clauses are *adverbial* modifiers, i.e. they play the same roles in sentences as do adverbs, so for practical purposes they *are* ad...

It is very common for English-speakers to say Just because you are rich doesn't mean that you can boss people around. However, the subject of a sentence should not begin with 'because'; it is fine, however to begin with (the fact) that or even with a gerund That you are rich does not mean that you ...

I like that -- bossy verb :) I wouldn't consider this a "command subjunctive"... but "command subjunctive" is just a term made up to help you remember that one of the structures that requires subjunctive is a command ("The prof demanded that we be in our seats by 8:00, for e...

Good question. Lots of people don't care about this rule in real life, but the issue is that we need to say "as a result of [noun]." "The sun shining" is not a noun... "the sun" is a noun, but not "the sun shining." HOWEVER, if we tack on an 's, then we're oka...

It's "does she have a car?" -- The verb "does" here is the main verb, so it's what's getting conjugated according to the subject "she" -- that's why we say "does" instead of "do" -- "she does," not "she do." The other verb then ju...

Another method: This is an evenly spaced set (i.e. all the intervals between entries are identical), so it's easy to find its average value: it will just be the middle entry, 200. The sum of all the entries will equal the number of entries times the average (think of the average formula: average = (...

You want the sum of the even integers 100, 102, 104, ..., 296, 298, 300. One method. Pair up these numbers working from the ends in, e.g. 100 , 102 , 104 , ..., 296 , 298 , 300 . Notice that each pair has the same sum, 400. Now determine how many pairs there are. Well, there are 201 integers from 10...

Added note: the problem hopefully says (or should say, if it doesn't) something like "What is one possible value of k?" We're told that X<Y, which again means that the average must land higher than the midpoint of 10 and 20 (the Y tests on which we got 20 points are pulling the average clo...

This method isn't very rigorous/algebraic, but it's a nice shortcut. First of all, just to clarify, the problem intends to have parentheses around the X+Y, right? So that the whole X+Y is in the denominator? (As opposed to how it's written above, which would have us just simplifying X/X to 1 before ...
