Step-by-step explanation:

3/4 (12x+8)=-13- (2x+3)

Answers

Answer: = − 2

Step-by-step explanation:

Remove parentheses.

3/4 (12x+8)=−13−2x−3

Simplify 3/4(12x+8) to 3(12x+8)/4.
3(12x+8)/4=-13-2x-3

Factor out the common term 4.
3x4(3x+2)/4=-13-2x-3

Simplify 3×4(3x+2) to 12(3x+2).
12(3x+2)/4=-13-2x-3

Simplify 12(3x+2)/4 to 3(3x+2)
3(3x+2)=−13−2x−3

Simplify −13−2x−3 to −2x−16
3(3x+2)=−2x−16

Expand
9x+6=−2x−16

Add 2x to both sides.
9x+6+2x=−16

Simplify 9x+6+2x to 11x+6.
11x+6=−16

Subtract 6 from both sides.
11x=−16−6

Simplify −16−6 to −22
11x=−22

Divide both sides by 11.
x=− 22/11

Simplify 22/11 to 2.
x=−2

-3(1+6r)=14-r


in class need help

Answers

Answer:

r = -1

Step-by-step explanation:

-3(1+6r)=14-r

Distribute the -3

-3*1 -3*6r = 14-r

-3 -18r = 14 -r

Add 18r to each side

-3-18r+18r = 14-r+18r

-3 = 14+17r

Subtract 14 from each side

-3-14 = 14+17t-14

-17 = 17r

Divide by 17

-17/17 = -17r/-17

-1 =r

Chase plans to buy a new car and determines he can budget $725 monthly for four years. His bank is offering an 8 25% annual interest rate What is the maximum loan he can afford to stay in his budget? Use the formula, A = (p[(1 + r/n) ^ m - 1])/(1/n * (1 + r/n) ^ N) , where Pis the monthly payment, the annual interest rate, nis the number of times interest is compounded in one year and is the number of years.

Answers

Answer:

$29555.20

Step-by-step explanation:

Given that:

P = $725

r = 8.25% = 0.0825

n = 12

t = 4 years

From the given formula:

[tex]A = \dfrac{P{(1+\dfrac{r}{n})^{n*t}-1 } }{\dfrac{r}{n}(1+ \dfrac{r}{n})^{nt}}}[/tex]

[tex]A = \dfrac{725{(1+\dfrac{0.0825}{12})^{12*4}-1 } }{\dfrac{0.0825}{12}(1+ \dfrac{0.0825}{12})^{4\times 12}}}[/tex]

[tex]A = \dfrac{725{(1.3894-1 )} } { 0.006875 \times 1.3894 }[/tex]

A = $29555.20

A store marks up a laptop 150% from its original price of $299. There is a sale for 25% off all items in the store. What is the sale price for the computer?

Answers

Answer:

B. 336. 38

Step-by-step explanation:

So, what you want to do is multiply the original price ($299) by the first markup percentage (150%)

299*1.50= $448.50

that is your markup price!

then you have to do the sale % (25%)

so you'll multiply your (25%) by your new price ($448.50)

448.50*.25= $112. 125

THIS IS NOT YOUR ANSWER!

don't forget that!

you will then subtract the sale price ($112.125) by the upcharged price ($448.50)

448.50-112.125= 336. 375

Round up then there is your answer!

= $336. 38

10. Write an expression in simplified form to
represent the area of the trapezoid.

Answers

Answer:

48[tex]x^{7}[/tex]y

Step-by-step explanation:

The area (A) of a trapezoid is calculated as

A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )

where h is the height and b₁, b₂ the parallel bases , then

A = [tex]\frac{1}{2}[/tex] × 4[tex]x^{5}[/tex] × (9x²y + 15x²y )

   = 2[tex]x^{5}[/tex] × 24x²y

   = 48[tex]x^{7}[/tex]y

The simplified expression for the area of the trapezium is 30[tex]x^7y[/tex] + 18[tex]x^7[/tex][tex]y[/tex].

What is trapezium?

A trapezium is a quadrilateral with four sides where two sides are parallel to each other.

We have,

Trapezium.

Height = 4[tex]x^5[/tex]

Parallel sides are 15x²y and 9x²y.

The area of the trapezium.

= 1/2 x h x ( sum of the parallel sides )

Now,

Area of the trapezium.

= 1/2 x 4[tex]x^5[/tex] x (15x²y + 9x²y)

= 2[tex]x^5[/tex] x (15x²y + 9x²y)

= 30[tex]x^7y[/tex] + 18[tex]x^7[/tex][tex]y[/tex]

Thus,

The area of the trapezium is 30[tex]x^7y[/tex] + 18[tex]x^7[/tex][tex]y[/tex].

Only the first point lies on the line and thus, Anders is incorrect

Step-by-step explanation:

Here, we want to show that Anders is incorrect

we simply substitute the values of his coordinates into the equation of the line

for (10,420)

we have;

420 = 40(10) + 20

420 = 420

This is right

We now test the second given point;

-420 = 40(-10) + 20

-420 = -400 + 20

-420 is not -380

How did labor unions and African Americans intersect during the era? What role did black people play in strikes? Points to consider:Although the Knights of Labor allowed black membership, by the 1890s the organization had lost influence to the American Federation of Labor. Founded in 1886, the AFL was ostensibly open to all skilled workers, but most of its local craft unions barred women and black tradesmen. In contrast, the United Mine Workers (UMW), formed in 1890, encouraged black coal miners to join the union rather than serve as strikebreakers. By 1900 approximately 20,000 of the 91,000 members of the UMW were black men. The Industrial Workers of the World, a revolutionary labor organization founded in 1905, brought black laborers and white laborers together. In 1869 a Baltimore ship caulker, Isaac Myers, organized the National Colored Labor Union, which lasted for seven years. Black stevedores periodically went on strike in Charleston, Savannah, and New Orleans. The Longshoremens Protective Union in Charleston won several strikes in the 1870s. In Nashville in 1871 black dockyard workers went on strike, demanding 20 cents an hour.2. What was the educational debate between Booker T. Washington and W. E. B. Du Bois?
