(3n-4n+1)-(8n-4n+17)

Answers

Answer 1

Answer:

-5n - 16

Step-by-step explanation:

Step 1: Distribute the negative sign.

[tex]3n - 4n + 1 + (-1)(8n) + (-1)(-4n) + (-1)(17)[/tex] [tex]3n - 4n + 1 - 8n +4n - 17[/tex]

Step 2: Combine like terms.

[tex](3n-4n-8n+4n)+(1-17)[/tex] [tex]-5n - 16[/tex]

Therefore, the answer is -5n - 16.

If m<18 = 46° and m<13 = 69°, calculate m<10.

Answers

Answer:

m<10 = 65°

Step-by-step explanation:

I. Given m<18 = 46deg, m<13 = 69deg and m<10 = x

The degree is less than 90deg, so this triangle is acute triangle.

Sum of degree inside of triangle is 180°

So 46 + 69

= 115

Find x by

180 - 115 = 65

So m<10 = 65°

- 5   (third answer down)

Step-by-step explanation:

12 + 12n = -48

subtract 12 from both sides

12n = - 60

divide both sides by 12

n = - 5

12+12n=-48
Subtract 12 from both sides of the equal signs
12n= -60
Now divide 12 on both sides of equal signs to get variable by itself
n= -5

Use the figure below to answer the following questions.
What is m∠1?
60
30
90
120

Answers

Answer:

30

Step-by-step explanation:

1. The exterior angle theorem states that the two opposing (in terms of the exterior angle) interior angles of a triangle are congruent to the exterior angle. This means that m∠1 (x) + 90 = 120. Now, we just have to solve for x.

2. (Solving)

Step 1: Subtract 90 from both sides.

[tex]x + 90 = 120[/tex] [tex]x - 90 = 120 - 90[/tex] [tex]x = 30[/tex]

Step 2: Check if solution is correct.

[tex]30 + 90 = 120[/tex] [tex]120 = 120[/tex]

Therefore, m∠1 = 30 degrees.

Answer:

∠ 1 = 30°

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

120° is the exterior angle of the left triangle , then

∠ 1 + 90° = 120° ( subtract 90° from both sides )

∠ 1 = 30°

Answer:

x = {0; 2}

Step-by-step explanation:

Given equation:

4x² - 8x = 0

Simplify and factorize:

x² - 2x = 0x(x - 2) = 0x = 0, x - 2 = 0 ⇒ x = 2

Answer:

[tex]x=0, \quad x=2[/tex]

Step-by-step explanation:

Given quadratic equation:

[tex]4x^2-8x=0[/tex]

Factor out the common term 4x:

[tex]\implies 4x(x-2)=0[/tex]

Therefore:

[tex]\begin{aligned}4x & = 0 & \quad \textsf{or } \quad (x-2) & = 0\\\implies x & = 0 & \implies x & = 2\end{aligned}[/tex]

Joan can't quite read the board in her math class. She writes down the equation she reads on the
board as 3x – 7 = 38. She correctly solves the equation she wrote down, but is surprised to hear the
teacher say the answer is 6 less than the answer she found. When she asks the teacher to check her
work, the teacher says that Joan copied the coefficient of x incorrectly (but copied everything else
correctly). What should the coefficient of x have been?

Answers

Answer:

x = 15

Step-by-step explanation:

3x - 7 =38

3x = 38+7

3x = 45/3

x = 15

The correct coefficient of x is 5 and the correct equation is 5x-7=38.

What is an equation?

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

The given equation is 3x-7=38.

Solution to given equation is

3x=38+7

3x=45

x=15

The teacher say the answer is 6 less than the answer she found.

Which is x=9

The teacher says that Joan copied the coefficient of x incorrectly

If equation is 5x-7=38

5(9)-7=38

38=38

Therefore, the correct coefficient of x is 5 and the correct equation is 5x-7=38.

The federal government is considering some fiscal policy alternatives. Will its choice between the following pairs of policy changes influence the level of aggregate demand, and if so how? a) An increase in taxes of 100 versus a reduction in transfer payments of 100. b) An increase in highway construction of 100 versus an increase in Social Security benefits of 100. c) A reduction in military procurement of 100 versus a reduction in scientific research of 100. d) A reduction in mass transit programs of 100 versus a tax increase of 100. 2. Consider an economy in which the marginal propensity to consume is two-thirds, prices are constant, the multiplier is three, G is initially 1,000, taxes are autonomous (not related to income) and are initially 1,300, transfer payments are initially 300, and GDP is initially 7,000. a) The government wishes to increase GDP to 7,300, and it is considering changing government purchases, or taxes, or transfer payments. What new levels of these fiscal policy tools would be needed?

Which statement from the passage supports the idea that Nelson Mandela was a courageous man?Nelson Mandela Nelson Mandela is known throughout the world for his fight against apartheid, the separation of blacks and whites. In 1944, while in his 20s, Mandela joined the African National Congress (ANC). The ANC was a political organization that fought against the racist policies of the South African government. Mandela led a peaceful resistance against the South African government for 20 years. He implemented strategies such as boycotts, strikes, civil disobedience, and non-cooperation. As a leader of the ANC, Mandela fought for blacks to have the right to vote and to travel without the use of documents called dompas. Mandela also fought for workers' rights and for free education for children of all colors. In 1960, the South African government banned the ANC. The organization went underground. Mandela decided that peaceful resistance was ineffective in the fight to end apartheid. He began supporting militant or aggressive actions against the South African government. In 1962, Mandela was arrested for leading a national workers' strike. The South African government sentenced him to five years in prison. While in prison, Mandela was charged with sabotage and was sentenced to life in prison. The South African government had hoped that locking Mandela behind bars would discourage his followers. However, Mandela became a symbol for the anti-apartheid movement. In 1985, President P. W. Botha tried to make a deal with Mandela. He offered to set Mandela free if Mandela agreed to call off the armed fight against apartheid. Mandela immediately declined this offer. In 1989, Frederik Willem de Klerk became the president of South Africa. He released Mandela from prison in 1990 and lifted the ban on the ANC. After spending 27 years in prison, Mandela continued to pressure the South African government to end apartheid. He called on foreign leaders to join him in the fight for blacks to have the same rights as whites. Mandela also continued to support the ANC's use of weapons against the South African government. Mandela worked with President F. W. de Klerk to establish the first multiracial elections in South Africa. In 1993, both men received the Nobel Peace Prize for their efforts to end apartheid. The government of South Africa held the first democratic elections in 1994. Nelson Mandela won the election and became the first black president of South Africa. A. Nelson Mandela won the election and became the first black president of South Africa. B. In 1944, while in his 20s, Mandela joined the African National Congress (ANC). C. After spending 27 years in prison, Mandela continued to pressure the South African government to end apartheid. D.
