### Scribe Post for January 12

Monday, January 12, 2009
okay today in class Mr.Harbeck gave us some questions to help us with the test *hint**hint*
these are the pre test help questions:
n-6= 14
n+9= -4
-9+n= 17
25= -12+n
n- (-6)= 15
-n/ 3= 6
-30n = 180
1/4n= 12
-n/ 3=12
12n=48

Now I am pretty sure that most of these questions will be on the test...Harbeck made that very clear in class.

The first question that I will be doing is 12n=48
first you isolate the n. Since it is multiplication you have to divide.

What ever you do to one side you have to do to the other.

n=4 find to the nth value
12n=48
12(4)=48 rewrite the question with the nth value
48=48 compare
Now I will be doing is 1/4n=12
first of all 1/4 n is the same as n/4 and 1 n/4, but you would never write the 1because you can't do that on the test. So,
n/4=12
now you have to isolate the n so since we are dividing we have to multiply
(4)n/4=12(4)
n=48 find to the nth value
n/4 =12
48/4=12 rewrite the question with the nth value
