(24y^5)/(15x^8) * 4x^4/(8y²) 

<span>Reduce the common factors for the numerator and denominator and multiply the fractions altogether to get... </span>

<span>24/8 * y^(5 - 2) * 4/15 * 1/x^(8 - 4) </span>
<span>= 3y³ * 4/15 * 1/x^4 </span>
<span>= 4y³/(5x^4) </span>

<span>I hope this helps!</span>

Answer:  The required simplified form is \dfrac{5x^4}{4y^3}.

Step-by-step explanation:  We are given to find he simplified form of the following division :

\dfrac{15x^8}{24y^5}~~~\textup{divided by}~~~\dfrac{4x^4}{8y^2}.

We know the following method :

\dfrac{a}{b}\div \dfrac{c}{d}=\dfrac{a}{b}\times\dfrac{d}{c}.

Also, we note the following rule of exponents :

\dfrac{x^a}{x^b}=x^{a-b}.

The simplification of the given division is as follows :

\dfrac{15x^8}{24y^5}~~~\textup{divided by}~~~\dfrac{4x^4}{8y^2}\\\\\\=\dfrac{15x^8}{24y^5}\div \dfrac{4x^4}{8y^2}\\\\\\=\dfrac{15x^8}{24y^5}\times\dfrac{8y^2}{4x^4}\\\\\\=\dfrac{5\times2}{8}\times\dfrac{x^{8-4}}{y^{5-2}}\\\\\\=\dfrac{5x^4}{4y^3}.

Thus, the required simplified form is \dfrac{5x^4}{4y^3}.

Interior and Exterior Triangle Angles<br><br> please help asap !!!!
Fiesta28 [93]

Answer:

∠ WUV = 36°

Step-by-step explanation:

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

∠ VWX is an exterior angle of the triangle, thus

8x - 18 = 2x + 8 + 3x + 16

8x - 18 = 5x + 24 ( subtract 5x from both sides )

3x - 18 = 24 ( add 18 to both sides )

3x = 42 ( divide both sides by 3 )

x = 14

Thus

∠ WUV = 2x + 8 = 2(14) + 8 = 28 + 8 = 36°

If -13x-71=201 what is x
jenyasd209 [6]

Answer:

272/-13 or −20.923

Step-by-step explanation:

To solve this equation you need to isolate the variable.

First, add 71 to both sides

-13x-71+71=201+71

-13x=272

Then, divide both sides by -13

-13x/-13=272/-13

So, x=272/-13 or −20.923
