In Mr.Gerson's 3rd per. class on Friday, we learned the properties of inequality. a < b = ac < bc its the same as the property of equality (a=b is the same as ac=bc), but with an inequality sign < or > etc.
Today in class we discussed and took notes on Solving Linear Inequalities in One Variable. The two properties that we used are Addition Property of Inequality and Multiplication Property of Inequality.
These some examples that we did in class:
F.) Each student agreed to sell at least 50 seed packages for a school project. Yesterday a student sold 22 packages, and today this student sold 18 packages. How many more packages does this student need to sell to reach the goal of 50 packages?
n = number of packages
22+18+n is greater than or equal to 50 packages
n + 40 is greater than or equal to 50 packages
subtract 40 from both sides
n is greater than or equal to 10 packages ____________________________________
G.) In an algebra course you must get a total of at least 360 points on four test for a grade of A. You get 85, 89, and 92 on the first three test. What score on the last test will give you an A?
Journal entry: Today we learned about solving linear inequalities in one variable. We set up an inequality for the word problems to solve them.
example: f) Each student agreed to sell at least 50 seed packages for a school project. Yesterday a student sold 22 packages, and today this student sold 18 packages. How many more packages does this student need to sell to reach the goal of 50 packages?
n=how many more seed packages
22+18+n is greater than or equal to 50 packages
40+n is greater than or less than 50 packages
use addition property of inequality to get rid of 40 from n
i dont understand how to do number 15 on 9-19 odd. can someone please help me? Your quiz grades are 73,75,89,91. what is the lowest grade you cane obtain on the last quiz and still achieve an average of at least 85%?
Today in 2nd period, we took notes on solving linear inequalities in one variable. We learned how to set the equation and solve word problems with using inequalities.
-Some exaples to help you understand this section that we did not go over in class:
1)A NUMBER M IS AT LEAST 3. HINTS:"at least" means the number could be 3 or greater. so the answer would be, M IS GREATER THAN OR EQUAL TO 3.
2)A NUMBER P IS AT MOST 1/3. HINTS:"at most" means the number could be 1/3 or less. so the answer would be, P IS LESS THAN OR EQUAL TO 1/3.
THESE ARE SOME EXAMPLES THAT WE DID IN CLASS TODAY:
F)EACH STUDENT AGREED TO SELL AT LEAT 50 SEED PACKAGES FOR A SCHOOL PROJECT. YESTERDAY A STUDENT SOLD 22 PACKAGES, AND TODAY THIS STUDENT SOLD 18 PACKAGES. HOW MANY PACKAGES DOES THIS STUDENT NEED TO SELL TO REACH THE GOAL OF 50 PACKAGES OF SEEDS?
*If the number of the packages that the student needs to sell is n, then the equation would be,
22+18+n is equal to or greater than 50 packages
n+40 is equal to or greater than 50 packages.
Then, subtract 40 from both sides and you get
n is equal to or greater than 10 packages.
So the final answer would be
A: THE STUDENT NEEDS TO SELL 10 MORE SEED PACKAGES.
G) IN AN ALGEBRA COURCE YOU MUST GET A TOTAL OF AT LEAST 360 POINTS ON FOUR TESTS FOR A GRADE A. YOU GET 85, 89, AND 92 ON THE FIRST THREE TESTS. WHAT SCORE ON THE LAST TEST WILL GIVE YOU AN A?
*If the score you get on the fourth test is x, then the equation would be 85+89+92+x is greater than or equal to 360 points
x+266 is greater than or equal to 360 points
Then you subtract 266 points from both sides and you get
x is greater than or equal to 94 points. So the final answer would be
A; YOU NEED TO GET 94 POINTS OR BETTER ON THE FOURTH TEST IN ORDER TO GET AN A IN THE ALGEBRA CLASS.
srry i couldnt rite out the equation, i would hav but i couldnt put the inequality sign or put n+73+75+89+91 over 5, wel actualy i could, but it was kinda confusing...
Journal Entry for October 18, 2010. Gloria Kim. Period 4.
Today in Mr. Gerson's math class, we took notes on Solving Linear Inequalities in One Variable. This time, we used word problems, wrote them out into inequalities, and then solved them. I learned that "at least" would involve the greater than or equal to symbol, and "at most" would involve the less than or equal to symbol.
One of the two word problems that we solved in class was:
g) In an algebra course you must get a total of at least 360 points on four tests for a grade of an A. You get 85, 89, and 92 on the first 3 tests. What score on the last test will give you an A. x = score for 4th test. 85 + 89+ 92 + x ≥ 360 x + 266 ≥ 360 - 266 ≥ -266 x ≥ 94 points.
@ gabriela i didnt get it either, but allie kinda helped me...i did this: n=integer n+(n+2)+(n+4)+(n+6)<35 umm...the anser is kinda confusing tho...lik if u look in the bak of the book...
In class today we took notes on Solving Linear Inequalities in One Variable with the Addition Property of Inequalitiy.
To solve a linear ineqaulity you: a.) label the unknown b.) make an equation c.) solve the equation d.) label the answer
An example we did in class today is:
g.) In an algebra course you must get a total of at least 360 points on four tests for a grade of A. You get 85,89,and 92 on the first 3 tests. What score on the last test will give you an A.
a.)x=the score of the 4th test
b.)85+89+92+x is greater than or equal to 360.
(add 85,89 and 92 and you get 266)
c.)266+x is greater than or equal to 360. (subtract 266 from both sides) d.)x is grearter than or equal to a 94 on the 4th test

The secongd problem we did was :
f.)Each student agreed to sell at leat 50 seed packages for a school project. Yesterday, a student sold 22 packages and today this student sold 18 . How many more packages does this student need to sell to reach the goal of 50 packages?
To solve this problem just use the steps from the first problem:
Today we learned about Solving Linear Inequalities in One Variable, which uses the Addition Property of Inequality and Multiplication Property of Inequality. For example:
F)Each student agreed to sell at least 50 seed packages for a school project. Yesterday a student sold 22 packages, and today this student sold 18 packages. How many more packages does this student need to sell to reach the goal of 50 packages?
N=number of packages
22+18+N is greater than or equal to 50 packages
N+40 is greater than or equal to 50 packages
Subtract 40 from both sides
N is greater than or equal to 10 packages!
G)In an algebra course you must get a total of at least 360 points on four test for a grade of A. You get 85, 89, and 92 on the first three test. What score on the last test will give you an A?
Today in Mr. Gerson's class, we were given 2 word problems and had to solve for each one.
1. Each student agreed to sell at least 50 seed packages for a school project. Yesterday a student sold 22 packages, and today this student sold 18 packages. How many more packages does this student need to sell to reach the goal of 50 packages?
n = number of packages
22+18+n is greater than or equal to 50 packages
n + 40 is greater than or equal to 50 packages
subtract 40 from both sides
n is greater than or equal to 10 packages

x = score of the 4th test
85+89+92+x is greater than or equal to 360 points
x + 266 is greater than or equal to 360 points
subtract 266 from both sides
x is greater than or equal to 94 points
throughout the period, we mostly talked about soccer.

JOURNAL ENTRY 10/18/10
@eric, i didnt know i had to do the journal post on friday. sorry!!
well...i put n=last test score... n+73+75+89+91 over 5 is greater than or equal to 85...so you can put that into an equation and solve it...
srry i couldnt rite out the equation, i would hav but i couldnt put the inequality sign or put n+73+75+89+91 over 5, wel actualy i could, but it was kinda confusing...
can anyone help me with nimber 17???
Is it ok if I post my journal entry tomorrow because I was out sick today?

how do u do number 29? anyone? ._.? help please.
#29 Hint:
A chain looks like this:
S-S-S.
S = section that can join other sections.
So the five chains:
S-S-S / S-S-S / S-S-S / S-S-S / S-S-S
Good luck.
i don't really get how number 29 relates to inequalities.
nevermind. i get how it has to do with inequalities.
why are you talking about 27? we didn't have to do it right?
@robert yes we did...
