Ok we need to solve for x.

First add 5 to both sides.
$\frac{5}{8}x = 10$
Divide $\frac{5}{8}$ from both sides
$x = 16$
(If you don't know how to divide fractions then comment or DM me)

The answer is x = 16

Hope this helped! If you have anymore questions or don't understand, please comment or DM me. :)

Select the correct answer. Rewrite the following expression.

kolezko [41]

The algebraic expression $x^{10/3}$ is equivalent to the algebraic expression $x^{3}\cdot \sqrt[3]{x}$ . Thus, the right choice is option D.

<h3>How to apply power and root properties to rewrite a given expression</h3>

In this question we must apply the following set of algebraic properties to simplify a given expression:

$x^{m/n} = \sqrt[n]{x^{m}} = \left(\sqrt[n]{x}\right)^{m}$ (1)

$x^{m+n} = x^{m}\cdot x^{n}$ (2)

$x^{m\cdot n} = \left(x^{m}\right)^{n} = \left(x^{n}\right)^{m}$ (3)

Where:

m, n - Exponents
x - Base

And also by apply the definition of power.

If we know that the given expression is $x^{10/3}$ , then the equivalent expression is:

$x^{10/3} = \sqrt[3]{x^{10}} = \sqrt[3]{x^{9}\cdot x} = \sqrt[3]{x^{9}}\cdot \sqrt[3]{x} = x^{3}\cdot \sqrt[3]{x}$

The algebraic expression $x^{10/3}$ is equivalent to the algebraic expression $x^{3}\cdot \sqrt[3]{x}$ . Thus, the right choice is option D.

Find the value of x , if log₂ [log₅ (log₃x)] = 0

Lina20 [59]

$\log_2 (\log_5( \log_3x)) = 0\\
D:x>0 \wedge \log_3x>0 \wedge \log_5(\log_3x)>0\\
D:x>0\wedge x>1 \wedge\log_3x>1\\
D:x>1 \wedge x>3\\
D:x>3\\
\log_5(\log_3x)=1\\
\log_3x=5\\
x=3^5\\
x=243$

Using the following grading scale and the following scores calculate the student’s final grade in the class: Tests: 55% Quizzes:

Artyom0805 [142]

Answer:

87.471

Step-by-step explanation:

Given that scores for test, quiz, final exam , average quizzes.

There are weight given as 55% for quiz, 30% for homework, 5% Final Exam 10% Tests:

Now to calculate the student final grade, we can use weighted average method.

Final exam average

100

75.71428571

Use the averages to find:

Score Weight Score*weight

Quizzes 90 55% 49.5

Homework 85 30% 25.5

Tests 75.71 10% 7.571

final exam 98 5% 4.9

total 87.471

Hence answer is 87.471
