Answer:
Total people = 240
Step-by-step explanation:
Let the total number of people by 'x'.


Number of children = 100
When we subtract the total number of men and women from the total people 'x', we get the number of children.



x = 20 * 12
x = 240
<h3> Total number of people = 240</h3>
<span>Let x represent the number of pairs of socks purchased,
and let y represent the number of blouses purchased.
</span><span>socks that cost $2.99 for each pair
and blouses that cost $12.99 each
equation
2.99x + 12.99y = 43.92</span>
One of the equations for a circle is (x - h)² + (y - k)² = r² where (h, k) are the center and r is the radius.
So after substitution:
(x + 6)² + (y - 2)² = 100
Notice the equation has the opposite of h and k and 100 is the result of squaring 10.
