Well first of all we would have to find 1% of the total seats
but first we need to understand that 38% arent sold, and there are 17,100 left. So to find 1 % we divide 17,100 and 38 so lets do that math:)
17,100 ÷ 38 = 450
so now we know that 1% = 450 seats
lets multiply that by 100 to get how many seats that are in the arena...
450 x 100 = 45,000
so there are 45,000 seats in the arena
hope this helps:)

Answer:
(3, 12)
Step-by-step explanation:
x + y = 15
x - y = -9
add them together
2x + 0y = 6
2x = 6
x = 6/2
x = 3
substitute 3 into any equation, i chose x + y = 15
3 + y = 15
y = 12
check for 2nd equation:
3 - 12 = -9
-9 = -9
To fond the area of a trapezoid, add the top and bottom together, divide that by 2, than multiply by the height.
Area = (8+12)/2 = 20/2 = 10
10 x 9 = 90 square centimeters.
