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

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

• Math -

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

on questin 1 the number was cut off the page i guessed it was either 6 or 7
