Reduce the Fraction: a(x-2y)/b(2y-x)

Answers

Answer:

[tex]\displaystyle-\frac{a}{b}[/tex]

Step-by-step explanation:

We have:

[tex]\displaystyle{\frac{a(x-2y)}{b(2y-x)}[/tex]

In the denominator, we can factor out a negative 1. This yields:

[tex]=\displaystyle\frac{a(x-2y)}{-b(x-2y)}[/tex]

We can now cancel out the factor. Hence:

[tex]\displaystyle=-\frac{a}{b}[/tex]

Answer:

Option A: 11,1 is the correct answer.

Step-by-step explanation:

The absolute value is used in the given expressions.

The absolute value represents the values of a number or variable irrespective of its sign. This means that |x| = x and |-x| = 0

Given expression is:

[tex]|2x-5|[/tex]

Putting x=3

[tex]|2(-3)-5| \\= |-6-5|\\= |-11|\\=11[/tex]

Putting x=-3

[tex]|2(3)-5| \\= |6-5|\\= |1|\\=1[/tex]

Hence,

Option A: 11,1 is the correct answer.

Step-by-step explanation:

The right side is a ratio [tex]0.84:\frac{7}{15}[/tex] a ratio can be written as a fraction [tex]\frac{0.84}{\frac{7}{15} }[/tex] this means [tex]0.84[/tex] divide by [tex]\frac{7}{15}[/tex] which is the same as [tex]0.84*\frac{15}{7}=\frac{12.6}{7}[/tex] On the left, change the mixed fraction [tex]3\frac{1}{3}[/tex] to the improper fraction [tex]\frac{10}{3}[/tex] Then divide [tex]0.3d-1[/tex] by [tex]\frac{10}{3}[/tex] which is same as [tex](0.3d-1)*\frac{3}{10} =\frac{3(0.3d-1)}{10}[/tex] So the equation is now [tex]\frac{3(0.3d-1)}{10}=\frac{12.6}{7}[/tex] Now multiply both sides by 10 and 7:[tex](10)*(7)*\frac{3(0.3d-1)}{10}=\frac{12.6}{7}*(7)*(10)\\7*3(0.3d-1)=12.6*(10)\\21*(0.3d-1)=126\\6.3d-21=126\\6.3d-21+(21)=126+(21)\\6.3d=147\\d=\frac{147}{6.3}[/tex]

The national government is divided into three sections:executive, legislative, and judicial. Citizens age 18 and older are allowedto vote for president and the legislative branch. Turkeys government isbased on a constitution that was passed in November 1982. It has beenamended several times since then. In 2017, citizens voted to changethe constitution. One of the changes made the country a presidentialrepublic. Citizens now vote directly for a president who serves as bothhead of government and head of state. Before the change, the head ofgovernment was the prime minister, who was chosen by the presidentfrom among members of parliament.Turkeys government is secular, which means there is a separationbetween religion and government. In Southwest Asia, Turkey is one ofthe few countries that is mainly Muslim but does not use Islamic law.While Turkey has made progress in the rights of its citizens as part of theirefforts to join the European Union, there is still room for improvement.Turkeys citizens do not enjoy complete freedom of speech. It is a crimeto insult the Turkish nation and the president. Unfavorable press coverageof the military, Kurds, or Islam can also lead to arrests.The executive branch of Turkeys government is made up of the president and the cabinet. The president serves as head of state and head of government and is elected by the citizens for a five-year term with a two-term limit. The direct election of the president began in 2017 aftera constitutional amendment. Members of the cabinet are appointed bythe president. Turkeys legislative branch has one house called the Grand NationalAssembly of Turkey. The Assembly has 600 seats. Each seat is directlyelected by the citizens and serves for a five-year term. Turkey is dividedinto 81 provinces. Each province has representatives in the Grand National Assembly.Turkeys judicial branch is made up of the Constitutional Court, theCourt of Cassation, and the Council of State. The Constitutional Courthas 15 members3 appointed by the Grand National Assembly and 12appointed by the president. These judges are appointed for one 12-year,nonrenewable term with mandatory retirement at age 65. The main roleof the Constitutional Court is to make sure laws passed by the GrandNational Assembly are constitutional. The Court of Cassation has about390 judges who serve until retirement at age 65. The main purpose ofthe Court of Cassation is to give a final verdict after decisions made bylower courts are appealed. Finally, the Council of State is organized into15 divisions, each with its own division head and at least five members.These judges are appointed for a four-year term that can be renewed.The main purpose of the Council of State is to give a final ruling in administrative issues.
