Answer: 27

Andre tried to solve the equation 1/4 ( x + 12 ) = 2. What was his mistake? Explain.

1/4x = -10
x = -40

Answers

Andre’s first mistake was that he didn’t distribute properly or at all. Instead of using the distributive property to get rid of the parenthesis, he moved the x to the 1/4 and subtracted 12 to the other side. Mistakes continue to occur from there so the equation solved would be:
1/4 (x+12)=2
1/4x+3=2
1/4x=-1
x=-4

His mistake is that he does not open the bracket first. The value of the x is negative of 4.

What is a BODMAS rule?

BODMAS rule means for the Bracket, Order, Division, Multiplication, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.

Andre tried to solve the equation 1/4 ( x + 12 ) = 2.

First, open the bracket, then we have

[tex]\dfrac{x}{4} + \dfrac{12}{4} = 2[/tex]

On simplifying, we have

[tex]\dfrac{x}{4 } + 3 = 2[/tex]

Subtract 3 from both sides, we have

[tex]\dfrac{x}{4} = -1[/tex]

Multiply the equation by 4, we have

[tex]x = -4[/tex]

More about the BODMAS rule link is given below.

Which piece of evidence from the article BEST explains WHY support for the American educational system advanced during the economic challenges of the 1930s? (A) (B) (C) (D) Many leaders believed it was in the interest of states, and the whole country, to educate people. As work and society grew more complex, however, more people understood that a better education meant they would earn more money. Working-class families realized their children would benefit from more schooling. The goal was to keep more children and teenagers in school. This kept kids from taking jobs early and becoming competition for unemployed adults. With the support of government programs, war veterans from a variety of social classes went to college in record numbers. Read the following conclusion. As a result of public unease about the quality of schools in the 1960s, conservatives pushed forward radical changes to address these issues. Which sentence from the article provides the BEST support for the above statement? (A) (B) (C) (D) A series of reviews followed, accompanied by many proposed changes. The main concerns were the curriculum, achievement as measured by student test scores and teacher performance. In order to clarify what was expected of teachers and students, states increasingly detailed curricula and set competency standards. More schools added computer-assisted instruction systems, which offered interactive lessons on a one-on-one basis.

(A) (B) (C) (D) by discussing how the rich have received a better education since the start of public education despite efforts to create greater equality for all students by arguing that education is best when it is free and accessible for everyone, despite a person's race, ability or gender by showing that the education system was founded on an American ideal of equal opportunity and has since been shaped by policies responding to historical changes by showing how students are better off when they are instructed with rigorous, standards curricula and take standardized tests to ensure their academic achievement Conservatives thought schools should focus on the basics by emphasizing traditional schooling and clearly defined standards. Which of the following BEST explains HOW the liberal perspective is different? (A) (B) (C) (D) Liberals believed that standardized testing would hurt the development of students by decreasing their self-confidence. Liberals advocated for open schools for students where whole-group instruction and testing were not used. Liberals advocated for more structured classrooms where students could personalize their learning by customizing the curriculum. Liberals felt the "back to basics" approach to learning would hurt students but agreed that standardized testing was important.
