Using a system of equations, it is found that the correct option is:
A) 1389x+1660y=787x+1121y.
<h3>What is a system of equations?</h3>
A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In this problem, considering the amounts in each olympics(1389 men and 787 women participated on the 19th, 1660 men and 1121 women in the 22th), the system is:
A) 1389x+1660y=787x+1121y.

Answer:
2:30 pm
Step-by-step explanation:
In two hours (from 10am), she is 45 * 2 = 90 miles from vacation cabin.
From then on her average is still 45 mph and her husband's is 65 mph. So, husband catches her 20 miles (65-45=20) in every hour.
<em>The husband has to catch up 90 miles. How long would it take if he is catching up at 20 miles an hour?</em>
<em>90/20 = 4.5 hours</em>
<em />
<em>So husband starts at 10am and 4.5 hours form that time is 2.30pm</em>
The length and width of the television could be any two numbers whose product is 70.
1 year 800
8=1%
4.5%= 36
2 year 836
8.36=1%
4.5%=37.62
3 year 873.62
1%= 8.73
4.5%=39.28
4 year 912.89
1%.=9.12
4.5%=41.04
5 year 953.93
The answer is $36.22 because you need to times 21.95 by 0.65 and you get 14.27 and add that to the original price.
