what we did in pre-algebra nov. 1

HELLO,
Today in per-algebra class we did the following POD:

POD 11/1
An old lady wants to give her grandchildren her tresure. She has 135 gold coins and 105 esmeralds. She wants to give all them away.
a) what is the maximum number of grand children that can recieve an identical amount of esmeralds and coins?
b) how many esmeralds will each children get?
so the answer to the pod is the followingthe old lady can give it to 15 of her grandchildren for letter a, you can find this if you do a factor tree. and for leeter b she can give 7 esmeralds because if you divide15 into 105 you will get 7-

If you can try to find the GCF. We work on finding the GCF:
a. 24 and 60 and 18
b. 16x and 4x
c. 20xyy and 8xxy

We work on factoring Algecraic Expressions
5x + 45 = 5(x + 9)
- First to solve this problem you find the Gcf of 5 and 45.
The GCF= 5
-Second divide 5x and 45 by the GCF.
5x: 5= x and 45: 5= 9
-Then write the Gcf in the front of the parethesis
5( )
-Then put the solution of the division of the Gcf and the numerator
5( x + 9)
-This is the algebraic expression of 5x + 45=

Try to solve the following:
36 - 4x=

THEIR IS NO HOMEWORK FOR TONIGHT!!!!!!!!!!!!!!!!!!!!!!!!!!!!

THE NEW SCRIBE IS MARCO

Karol,

Thanks for getting your post on.

Buuuuuuttttt,

you should show how to solve the POD by making some factor trees and explain why the GCF solves the problem. As it stands now, your post is not that helpful for someone who does not already know how to do the problems.


Well done lady pirates and well fought gentlemen pirates.
