Step-by-step explanation:

[tex]11x \times x = 539 \\ 11 {x}^{2} = 539 \\ \frac{11x}{11} = \frac{539}{49} \\ {x}^{2} = 49 \\ \sqrt{ {x}^{2} } = \sqrt{49} \\ x = 7[/tex]

The oranges are 7

And the melons are 11 times the number of the oranges hence

Using percentages we know that the total price of the book that Tommy will pay is $131.04.

What is the percentage?

In mathematics, a percentage is a number or ratio that is expressed as a fraction of 100.

Although "pct," "pct," and occasionally "pc" are also used as abbreviations, the percent symbol "%" is most usually used to denote it.

A% is a number that has neither dimensions nor a defined unit of measurement.

For instance, if you properly answered 75 out of 100 questions on a test, you would have received a 75% grade (75/100).

So, we know that the price of the book is 180.

Sales tax is 4%. So, the total price:

180/100 * 4 = 7.2$ ⇒ $187.2

Now, there is a 30% discount:

187.2/100 * 30 = $56.16

⇒ 187.2 - 56.16 = $131.04

Therefore, using percentages we know that the total price of the book that Tommy will pay is $131.04.

The tens digit of a certain two-digit number is 1/3 of the units digit. When the digits are reversed, the new number exceeds twice the original number by 2 more than the sum of the digits. Find the original number.

Step-by-step explanation:

To prove that AC = BD, we can use the symmetric property. The symmetric property states that if two quantities are equal, then their opposites are also equal.

In this case, we are given that AB = CD. Since AB and CD are opposite quantities (they are the lengths of the diagonals of a rectangle), we can use the symmetric property to conclude that AC = BD.

Therefore, the reason that can be used to justify statement 4 in the proof is the symmetric property.

The solution of the equation for values of a is 1/(x - 1)

From the question, we have the following parameters that can be used in our computation:

a^2x - a = ax

Rewrite properly as

a²x - a = ax

Divide through by a

So, we have

ax - 1 = x

Collect the like terms

ax - x = 1

Factor out x

This gives

a(x - 1) = 1

Divide both sides by x - 1

a = 1/(x - 1)

Answer:

Step-by-step explanation:

The inverse function for this problem is defined as follows:

P^(-1)(x) = square root of (x + 100/5), x ≥ -100.

The function in this problem is defined as follows:

P(x) = 5x² - 100, x ≥ 0.

In which P(x) is the profit earned when x tamales are sold.

To obtain the inverse function, first we exchange the variable y = P(x) and x are follows:

x = 5y² - 100

Then the variable y must be isolated as follows:

5y² = x + 100

y² = (x + 100)/5

y = square root of (x + 100/5).

The domain must be the same domain of the square root function, that does not accept negative values hence:

P^(-1)(x) = square root of (x + 100/5), x ≥ -100.

This means that the first option is correct.
