5 numbers chosen from 25 can be done in 25C5 = 25!/(5!*20!) = 53,130 ways. The probability of choosing the correct set of 5 numbers is
1/53,130
Answer:
It passes through the point (3,4). Given that the center of the circle is the point (0,0). We know that the equation of the circle is given by : (x-a)^2 + (y-b)^2 = r^2 where (a,b) is the center and r is the radius.
I’m pretty sure that the answers

De acuerdo con todas las leyes de aviación conocidas, no hay forma de que una abeja pueda volar. Sus alas son demasiado pequeñas para despegar su pequeño cuerpo gordo. La abeja, por supuesto, vuela de todos modos. Porque a las abejas no les importa lo que los humanos piensan que es imposible
So for me, how I would do it is move the variables and numbers to one side. So we have the equation 3x-3=2/5x+7. So you would subtract 2/5x to the left side and add 3 to the right side. The equation will then turn out to be 3x-2/5x=7+3. Much more easier right? So just simplify both side, and you will get 13/5x=10. In order to isolate x, you have to divide 13/5 in both side, leaving x= 3 11/13 or 50/13. You can always plug the answer back in to double check :)
