The document provides instructions for solving basic equations using addition and subtraction. It explains that to solve an equation means to isolate the variable by using the property of equality, where any operation done to one side must also be done to the other side. It then walks through examples of solving equations such as r + 16 = -7 by subtracting 16 from both sides to isolate r. It emphasizes drawing a "river" to separate the equation into two sides and checking the answer by substituting it back into the original equation.

Linear equation in one variable
Linear equations in one variable can be written in the form ax + b = 0, where a and b are real numbers and a ≠ 0. These equations have exactly one solution, also called the root of the equation.

Using Proportions to Solve Problems
Using proportions is an effective way to solve many application problems. A proportion states that two ratios are equal, such as the ratio of girls to boys in a class. To check if a proportion is true, you can verify if the cross products are equal. Cross products can also be used to solve proportions. Examples show how to use proportions to find costs, lengths, and expected outcomes by setting up ratios, labeling parts of the proportion, taking cross products, and solving. Similar triangles have proportional corresponding sides that can be used to find missing values.

The Russian Revolution overthrew the last Czar of Russia, Nicholas II, in 1917 due to public discontent with his leadership after years of war and hardship while the royal family continued to live in luxury. The revolution was inspired by the ideas of Karl Marx, whose belief that communism would emerge from class struggle resonated with revolutionaries like Vladimir Lenin and the Bolsheviks. After seizing power, Lenin established a communist government, but his death caused a power struggle between Leon Trotsky, who wanted to modernize Russia, and Joseph Stalin, who eventually consolidated power through deception and violence, establishing a totalitarian dictatorship and carrying out a brutal repression of dissent through the NKVD secret police that led to millions of deaths.
loan default by SHGs,, study based on case study
This dissertation submitted by Kaushal Kishor Kaushal to IIT Guwahati examines loan repayment in self-help groups (SHGs) in Assam, India. It analyzes the status and reasons for default between SHG members and banks. The study uses primary data collected from questionnaires with SHG members, as well as secondary data from institutions. It finds that while loan repayment in SHGs was over 95% until 2010, some recent research shows the rate has decreased to 88%, with factors like lack of economic activities and over-reliance on loans contributing to defaults. The dissertation acknowledges further work is needed to promote sustainability in SHGs.

What is-plagiarism 2
Plagiarism is presenting others' work as one's own without proper citation. Research shows that over 70% of students admit to some form of academic dishonesty such as cheating on tests or plagiarizing assignments. Plagiarism can be intentional, such as copying a friend's work, or unintentional through poor citation practices. Consequences of plagiarism range from failing grades to suspension and damage to one's academic and professional reputation.

Great Depression, edited
The document summarizes the key events of the Great Depression in the United States beginning in 1929. It describes how agricultural and industrial problems in the late 1920s led to a stock market crash in October 1929. This crash signaled the beginning of the Great Depression, a period from 1929 to 1940 when the economy plummeted and unemployment skyrocketed to 25%. As a result of the crash and ensuing Depression, banks collapsed, homelessness increased, and soup kitchens and makeshift shantytowns appeared across the country as millions lost their jobs and homes. Hardest hit were farmers in the Midwest who faced the additional crisis of the Dust Bowl drought.
Elizabethan shakes-rj2
The document provides context about William Shakespeare and his famous play Romeo and Juliet. It discusses life during the Elizabethan Era in England, including fashion, marriage, health, and education. It then focuses on Shakespeare, describing his upbringing, career, and some of his major plays. Finally, it summarizes the basic plot of Romeo and Juliet, including the two feuding families and star-crossed lovers whose love and marriage lead to tragedy.
Animal farm intro, edited
Animal Farm by George Orwell is an allegorical novella published in 1945 that satirizes the Russian Revolution and rise of Stalinism. Orwell was a journalist who hated totalitarianism and believed in democratic socialism. The story is inspired by the events of the Russian Revolution where the Bolsheviks overthrew the provisional government in 1917 and Lenin took control, followed by a power struggle after Lenin's death between Trotsky and Stalin. Animal Farm uses allegory and satire to attack Stalin and depict a totalitarian regime.
Russian revolution, edited
The Russian Revolution of 1917 overthrew the oppressive rule of Czar Nicholas II as the impoverished people grew angry with his leadership that benefited only himself while they starved. They were inspired by the political ideas of Karl Marx and formed the Bolshevik party led by Vladimir Lenin to establish a communist system with equal rights and resources for all. However, after Lenin's death, Joseph Stalin rose to power through deception and eliminated his opponents, establishing a totalitarian dictatorship worse than that of the Czar as he had millions killed through his secret police in his greedy pursuit of control.
Case summary
This document discusses a case study from a preschool class in a remote school in Ranau, Malaysia. It describes two main issues: 1) A very clever student who finishes tasks quickly and disturbs other students. 2) Some students have difficulty with reading, writing, and arithmetic skills due to delays in language acquisition.
To address these issues, several solutions were proposed. For the fast-finishing student, additional tasks were assigned to keep them occupied. For students struggling with skills, activities like alphabet games, colored syllables, reading words and cards, and a reading corner were introduced. Other teachers suggested appointing the fast student to help weaker students.
Short story notes
The document discusses key elements of short stories, including that they are fictional works that can be read in one sitting. It notes that short stories use elements like plot, setting, characters, theme, exposition, rising action, climax, falling action, resolution, and conflict to illustrate truths about life. It also discusses symbolism and different types of conflicts that may be present in short stories.
U.s. debt crisis
1. The United States debt ceiling crisis arose because the legal debt limit was reached in 2011, requiring Congress to raise the ceiling to allow further government borrowing.
2. High budget deficits and rising federal debt, exacerbated by economic recession, ongoing wars, rising healthcare costs, and lack of infrastructure investment caused the debt to rise rapidly.
3. Failure to raise the debt ceiling would have forced the government to cut spending by 40% and risk defaulting on loans, with severe economic consequences for the US and global economy.

Training and development is important for organizations to ensure learning and reduce randomness. Traditionally, organizations did not believe in training, but now recognize its importance. The objectives of training are to develop individual skills, achieve organizational goals, ensure functional department contributions, and ensure social responsibility. To make training effective, it is important for the training to be relevant to employees' jobs, for supervisors to support training transfer to the workplace, and for evaluations to measure training outcomes.

Here are the steps to solve this equation:
1) The equation is: x + 3 / 6 = 1
2) Multiply both sides by 6: x + 3 = 6
3) Subtract 3 from both sides: x = 3
Therefore, the solution is x = 3.
(d) The equation is: 3(y − 7) = 14 − y/2
3y − 21 = 14 − y/2
3y − 21 + y/2 = 14
