People who purchased good seats will be labeled as a
people who purchased poor seats will be labeled as b
therefore...
5a + 2b = 660
a + b = 210
Now, all that has to be done is for the system to be solved.
-2(a+b=210)
5a + 2b = 660
-2a - 2a = -420
3a=240
a= 80
*3 people purchased good seats.
Now we can plug that number in
5(80) + 2b = 660
400 + 2b = 660
2b = 260
b = 130
*130 people purchased poor seats
A circle exists as a curve sketched out by a point moving in a plane. The circle's perimeter exists the length of the line of the circle that creates the circle. It exists generally named the circumference of the circle.
<h3>What is a circle?</h3>
A circle exists as a curve sketched out by a point moving in a plane so that its distance from a given point exists constant; alternatively, it exists as the shape created by all points in a plane that exists at a set distance from a provided point, the center.
A.) The statement that rejects this characterization of the circle exists that the given point should be at the circle's center.
B.) An illustration of an indefinite term exists in the perimeter of the circle, The circle's perimeter exists the length of the line of the circle that makes the circle. It exists generally named the circumference of the circle.
