Given are three married couples.
So, let us assume there are 3 men and 3 women
They are sitting in a row of 6 empty seats
There is a definite order constraint that each woman will sit left to her husband. The first woman gets 3 options to choose from 3 available seats. The second woman has two options left as already one seat is filled by the first woman. The last woman has one option left. So, it is 
So, number of ways is 3! =
= 6 ways.
After solving the provided question, Aisha spent 7.9 hours and 9.9 hours, respectively, working last week as a babysitter and a landscaper.
<h3>Which is an equation?</h3>
A mathematical statement that has at least two terms, both of which contain variables or equal integers, is defined as an equation.
Aisha is reportedly working two summer jobs, earning $7 an hour for babysitting and $8 an hour for gardening.
Let's say you were to watch the children for x hours.
And y would be the amount of hours spent on landscaping.
Last week, Aisha spent two more hours babysitting than a landscaper, earning a total of $134.

Answer:
t = 42857.14 h
Step-by-step explanation:
Given that,
The speed of space shuttle, v = 28000 km/h
We know that, the distance between the Saturn and the Earth is 1,200,000,000 km.
Let t be the time.
As we know, speed = distance/time
So,

So, the required time is equal to 42857.14 hours.
