I need help with these 3 problems.

1. An amusement park charges admission plus a fee for each ride you go on. 2 admissions and 5 rides cost $22. 2 admissions and X rides cost $24. What is the charge for 1 admission and the charge for 1 ride.

2. Find the lenght of the hypotenuse of a right triangle with legs of length 6 and 10. Give you answer in simplest radical form.

3. Solve. 3x^2-5x-1=2

PLEASE HELP ME!!!

1. Where it says X rides, are you sure there is not a number there? There is not enough information in that problem the way it is written.

2. For right triangles, use the pythagorean theorem. a^2+b^2=c^2..6^2+10^2=? Then simplify that.

3. Use the quadratic formula: (-b+-sqrtb^2-4ac)/2a

Post your answers if you'd like them checked.

2a+5r=22

2a + xr = 24

I need to know x to solve for a and r.

h^2 = 6^2 + 10^2

h^2 = 136

h = 2 sqrt 34

x = [5 +/- sqrt(25+12)]/6

= [ 5 +/- sqrt (37)]/6
