Area = side * side
Area of the square = 6 1/9 * 6/1/9
= 36 1/81
62% because 200 silver coins out of 323 (total of all coins) is .619..., resulting in 62%
Answer:

Step-by-step explanation:

3x-4y=10
-20-x+2y=10 then -30+2y=x now plug this in the other equation:
3(-30+2y)-4y=10
-90+6y-4y=10
2y=100
y=50
(3x+2)-(2x-2)
3x+2-2x-2
3x-2x=x
2-2+0
X
