This Blog exists for the collective benefit of all algebra students. While the posts are specific to Mr. Chamberlain's class, any and all "algebra-ticians" are welcome. The more specific your question (including your own attempts to answer it) the better.
In #9, what happens if you simply do the division? Don't overcomplicate things... with out today's lesson, you would have simply divided, right?
For #24, if you are going to set up a proportion, you need an equal sign, right?
Consider this: - If the package of 10 razors cost $6.30, how much does each razor cost? - So .63/1 week = ??/ 1 day - What now?
#30 is just like the rate conversion problem we did in class. You want to re-state 60ft/sec in another unit of distance measure AND time measure. BUT (with one 't'), you don't want to change the value i.e. 60ft/sec... so you can only multiply by a BIG FAT ONE. The question is, which ONE do you choose?

for 21, 1 cm equals .393700787 inches.

Please round to two decimal places in your conversions... you should find conversion rates in your planners, yes?
ReplyDeleteThis seems stupid-- but how do I get all of the denominators in problem #9 to equal one so I can get the unit rate? :(
ReplyDeleteHow would I make #24 a proportion?
ReplyDelete6.30/1 week x 1 week/7days ?
How do you set up # 30 as a proportion?

Let me know if this helped.
Mr. C.
Why would 6.30 change to .63?
ReplyDelete$6.30 was for 10 razors... what's the cost of one razor?? (aka UNIT COST, the BIG FAT ONE of a coefficient in the prominator)
ReplyDeleteOh so you divide by 10
ReplyDelete[This is for HW 2-8]
ReplyDeleteHow would you make #29 on pg 154 an equation?
see post for hw #2-8
