8x + 47 = 8x + 40
No solutions (the above 2 expressions cannot be equal for any value of x)
The equation of a circle is (x-h)²+(y-k)²=r², with h being the x value in the center, k being the y value, and r being the radius. x and y can stay variables, so we can plug numbers in to get (x-0)²+(y-3)²=5²=25=x²+(y-3)²
There are 0.5 liters in 500 ml.
