List all the elements of each set. Set of the values of x that turn equation 0.7(x−7)−4.9=5.7 into a true statement

Paraphin [41]

Answer: 22.14 (22.1428571429)

Step-by-step explanation:

Let's Start with the equation

0.7(x−7)−4.9=5.7

Add 4.9 to both sides

0.7(x-7)=10.6

Divide both sides by 0.7

x-7= 15. 1428571429

Add 7 to both sides

x= 22.1428571429 or 22.14

Which expression is equivalent to (16 x Superscript 8 Baseline y Superscript negative 12 Baseline) Superscript one-half?.

loris [4]

To solve the problem we must know the Basic Rules of Exponentiation.

<h2>Basic Rules of Exponentiation</h2>

$x^ax^b = x^{(a+b)}$
$\dfrac{x^a}{x^b} = x^{(a-b)}$
$(a^a)^b =x^{(a\times b)}$
$(xy)^a = x^ay^a$

$x^{\frac{3}{4}} = \sqrt[4]{x^3}= (\sqrt[3]{x})^4$

The solution of the expression is $\dfrac{4x^4}{y^6}$ .

<h2>Explanation</h2>

Given to us

$(16x^8y^{12})^{\frac{1}{2}}$

Solution

We know that 16 can be reduced to $2^4$ ,

$=(2^4x^8y^{12})^{\frac{1}{2}}$

Using identity $(xy)^a = x^ay^a$ ,

$=(2^4)^{\frac{1}{2}}(x^8)^{\frac{1}{2}}(y^{12})^{\frac{1}{2}}$

Using identity $(a^a)^b =x^{(a\times b)}$ ,

$=(2^{4\times \frac{1}{2}})\ (x^{8\times\frac{1}{2}})\ (y^{12\times{\frac{1}{2}}})$

Solving further

$=2^2x^4y^{-6}$

Using identity $\dfrac{x^a}{x^b} = x^{(a-b)}$ ,

$=\dfrac{2^2x^4}{y^6}$

$=\dfrac{4x^4}{y^6}$

Hence, the solution of the expression is $\dfrac{4x^4}{y^6}$ .

Answer:

x = 6

Step-by-step explanation:

Since the given triangles ΔLMN and ΔCBQ are similar,

Their corresponding sides will be proportional.

$\frac{LM}{CB}= \frac{MN}{BQ}=\frac{NL}{QC}$

Since, $\frac{LM}{CB}= \frac{MN}{BQ}$

$\frac{(5x-6)}{6}=\frac{52}{13}$

5x - 6 = 24

5x = 30

x = 6

Therefore, x = 6 will be the answer.
