Answer:

see below

Step-by-step explanation:

12.5x − 10.2 = 3(2.5x + 4.2) - 6

Use the distributive property to distribute the 3

12.5x − 10.2 = 7.5x + 12.6 − 6

Combine like terms

12.5x − 10.2 = 7.5x + 6.6

Add 10.2 to each side of the equation by using the addition property of equality

12.5x = 7.5x + 16.8

Subtraction 7.5x from each side of the equation by using the subtraction property of equality

5x = 16.8

Divide by 5 on each side by using the division property of equality

x = 3.36

What is the simplified form of StartRoot StartFraction 72 x Superscript 16 Baseline Over 50 x Superscript 36 Baseline EndFractio

Iteru [2.4K]

The simplification form of the provided expression is 6/5x¹⁰ option first is correct.

<h3>What is an expression?</h3>

It is defined as the combination of constants and variables with mathematical operators.

We have an expression:

$\rm = \sqrt{\dfrac{72x^{16}}{50x^{36}}}$

$\rm = \sqrt{\dfrac{72}{50}} \sqrt{\dfrac{x^{36}}{x^{16}}}$

$\rm = \sqrt{\dfrac{36\times2}{25\times2}} \sqrt{\dfrac{x^{36}}{x^{16}}}$

$\rm ={\dfrac{6x^{8}}{5x^{18}}}$

$\rm ={\dfrac{6}{5x^{10}}}$

Thus, the simplification form of the provided expression is 6/5x¹⁰ option first is correct.

What is 106% of $= to $7.95

ankoles [38]

So, I'm not quite sure what you're asking, so I'll answer it two different ways.
7.95 + (7.95 * 1.06)
7.95 + 8.247 = $16.197

The second way:
1.06n = 7.95
n = 7.95 / 1.06
n = 7.5
106 Percent of $7.50 is 7.95
