Math: Khan Academy video
Journal Pg 83 #5 - #8 Due Wednesday, October 31
Dynamath due Tuesday, November 6, 2012
Mrs.sutton, on the Khan Academy worksheet do you use * or times? C.N
ReplyDeleteOn the worksheet for Khan academy do you use * or times? CN
ReplyDeleteCN - You can use a dot to show multiplication or an *, but you cannot an x for multiplication. You can also use nothing, such as 5t is the same as 5 * t.
ReplyDeleteWhen is the journal pg. due?

AD - Wednesday, Halloween morning.
ReplyDeleteHi Mrs.Sutton on the Khan acadamy ws there is a question that says "rewrite the second equation, insetingyour solution for x. Solve" What does that mean?
ReplyDeleteLR
LR - I believe what I want you to do is rewrite the second equation, inserting what you solved x for. Then solve. Example:
Delete3x * 9 = 54
x = 2
3 (2) * 9 = 54
6 * 9 = 54
Does that make sense?
On the Khan Acadamy WS, what do they mean by fractions? ( 3x/3 or 3 * 1/3? )
ReplyDeleteAD
AD - I read that in the comments section. Is that what you are referring to?
DeleteBasically, he is trying to show you how to isolate x. If it is 3x = 27, you have to isolate the variable (x). You can do that by dividing both sides by 3....
3x/3 = 27/3 -r x = 9
Another way to look at the same process is to multiply each side by 1/3, which is essentially the same thing as dividing both sides by 3.
If I multiply 1/3 * 3x = 1/3 * 27, I can read that as 3/3x = 27/3; x = 9.
We will go over that further in class.
Multiplying by 1/3 is the same as dividing by 3.
