Only 94 students completed the sample test by 9:30 this morning. Why would a student not want to take a form of the test in preparation for the chapter test? How was the sub?
yup i got a question for you number 42 and 43? 42 so the directions say to factor this 9a-9 and i got 3(3a-3) the book say its 9(a-1) am i wrong or right??? and its the same for number 43! the question say to factor 8x-32y-8 and i got 4(2x-8y-2) but the book says something different
i checked my work and both seemed to work but i was just wondering if im right or not!! please help!! thanks
Mr. Gerson, will you be at school tomorrow? Because I wanted to ask you some questions before the test if I could.. If not, hopefully you could answer them now.
Taylor, you are right but you can divide both 9's by a bigger number 9! so instead of dividing both by 3 divide both by 9, and you will get 9(a-1) ! *hope that helps!*
k so you would do number 42 by seeing what all the numbers have in common. so if the problem was, 9a-9, what do they have in common? 9. so you factor so 9a-9/9 so your final answer is 9(1-a), because you put the bottom number in the fraction on the outside and the top numbers in parenthesis in simplest form. so yea thats number 42...also check your work by using the distributive property!
I guess so........ because 1.we had most of the chapter wrap up for homework 2.mr. gerson says prepare for the test 3.we did another pratice test for chapter 2 so concluding from that I guess we're gonna have it tomorrow or sometime VERY soon........
For subtraction of a positive and a negative, is it like adding the numbers but the answer would be a negative? Also, If your adding or subtracting fractions, would you find a common denominator or just add/subtract it the way it is? And one more thing, if your subtracting 2 negatives, would you add them and make it a negative number or would you do something else? (Mr.Mendoza was Okay) :]
We have a test on Wednesday. (Today is Tuesday). By the way the sub was fine, but he rhymed a lot. Are you going to be at school tom., Mr. Gerson? Just to let you know Wynona, the problems are pgs 108-- 109 numbers 20--58.

Hey Mr.Gerson!!
Today Mr.Mendosa was great....but he was not better than you!!....

He was okay.

was the homework 108-109 20-58
i might have written down the wrong homework!
yea the sub was fine but do we really have all that home work???
The sub was good, just a normal sub
Umm. For the summaries for our notes what do they have to be about?
mr. mendosa was ok I guess
but we had a debate in class on which college is better; USC or UCLA...........
the sub was good.
can any1 help me with number 54? i don't get it!
THANX!!!
umm for taylor's problem
ok first start out with 9a-9
they can both be divided right? that is basically the gcf.
so it turns out as
9(a)+9(-1)
then
9(a-1)
Taylor, you are right but you can divide both 9's by a bigger number 9! so instead of dividing both by 3 divide both by 9, and you will get 9(a-1) ! *hope that helps!*
ok then number 43
start out with 8x-32y-8
again the gcf is 8 so divide all the numbers by eight
8(x)+8(-4y)+8(-1)
so it turns out as;
8(x-4y-1)
k so you would do number 42 by seeing what all the numbers have in common. so if the problem was, 9a-9, what do they have in common? 9. so you factor so 9a-9/9 so your final answer is 9(1-a), because you put the bottom number in the fraction on the outside and the top numbers in parenthesis in simplest form. so yea thats number 42...also check your work by using the distributive property!
yea so on 43 they all have 8 in common, use the highest divisible number as possible which is 8
is tommorow the chapter test?
ok so 54, the problem is 3p-4(8p-3).
First, use distributive property to get rid of the parenthesis, making it 3p-32p+12
Second, simplify all like terms so you would subtract 3p and 32p making it -29p
Lastly, there are no more terms that can be simplified so your answer is -29p+12
Taylor,
Both answers are right,but if the book says 9(a-1) just right that down
I guess so........
because
1.we had most of the chapter wrap up for homework
2.mr. gerson says prepare for the test
3.we did another pratice test for chapter 2
so concluding from that I guess we're gonna have it tomorrow or sometime VERY soon........

(Mr.Mendoza was Okay) :]
thanx anthony i get it now!!
thanks sooooooooooooooooooooo much for all your help
test is tomorrow..... i think
taylor your answer is right. i dont know why in the book the answer is 9(a-1)instead on 3(3a-3).i would ask mr. gerson in class tomorrow.
yes our hw is pg.108-109 #20-58
