In fractional form, I think this is written as

\frac{1}{x-10} / \frac{9x}{ x^{2} -9x-10}

When dividing, the first term is the dividend, the second term is the divisor and the answer is the quotient. When you divide fractions, you multiply the dividend with the reciprocal of the divisor. In this case

\frac{1}{x-10} * \frac{x^{2} -9x-10}{9x }

The answer is 

\frac{ x^{2} -9x-10}{9 x^{2} -90x}

Furthermore, we can simplify the terms through factoring, The numerator could be factored into (x+1)(x-10). The denominator could be factored to 9x(x-10). Since the term (x-10) is common, you can cancel them to get to the final answer which is

(x+1)/9x

Archy [21]
<span>Question: The diagonals of rhombus FGHJ intersect at point K. If side GH is equal to x + 9 and side JH is equal to 5x - 2, find x.
       
Answer: Rhombus
I have all of the properties of the parallelogram PLUS
- 4 congruent sides
- diagonals bisect angles
- diagonals perpendicular
       
3x - 10 = 6x - 19
3x - 6x = -19 + 10
-3x = -9
x = -9/-3

Mia is 7.02576 × 10^6 minutes old. Convert her age to more appropriate units using years, months, and days. Assume a year has 36
Naya [18.7K]

Answer:

Number of days = 4879 days

Number of months = 162.63 months

Number of years = 13.37 years

Step-by-step explanation:

Given

Mia's age (in minutes) = 7.02576 * 10^6

Required

Calculate age in years, months and days.

For ease of work, we'll start by converting to days.

First, it should be noted that there are 24 hours in one day

And there are 60 minutes in an hour.

This means that there are 24 * 60 minutes in a day

Number of minutes = 24 * 60 minutes

Number of minutes = 1,440 minutes

So, if number of minutes in a day is 1,440

Number of days in 7.02576 * 10^6 minutes is calculated as follows

Number of days = \frac{7.02576 * 10^6}{1440}

Number of days = 4879 days

Now, we can convert this to month and year, easily.

From the question, it should be assumed that there are 30 days in a month.

If 1 month = 30 days

Then, there are \frac{4879}{30} months in 4879 days

Number of months = \frac{4879}{30}

Number of months = 162.63 months

Converting to year

From the question, it should be assumed that there are 365 days in a month.

If 1 year = 365 days

Then, there are \frac{4879}{365} years in 4879 days

Number of years= \frac{4879}{365}

Number of years = 13.37 years
