Answer:
14/24 are ill so
58 percent
if you add 5 it does not get more complicated you just add 5 so 14/29
Hope This Helps!!!
Some equivalent fractions of 13 are <span>13/1 = 26/2 = 39/3 = 52/4 = 65/5 = 78/6 = 91/7 etc.

we have that
![2sin^{2} x-5sin x-3=0](https://tex.z-dn.net/?f=%202sin%5E%7B2%7D%20x-5sin%20x-3%3D0%20)
I. Rewrite the equation by substituting the expression u in for sin x.
![2u^{2} -5u-3=0](https://tex.z-dn.net/?f=%202u%5E%7B2%7D%20-5u-3%3D0%20)
II. Factor the quadratic expression. Rewrite the equation with factors instead of the original polynomial.
is equal to
using a graph calculator-----> see the attached figure
![(u-3)*(2u+1)=0](https://tex.z-dn.net/?f=%20%28u-3%29%2A%282u%2B1%29%3D0%20)
III. Use the zero product property to solve the quadratic equation.
![(u-3)*(2u+1)=0](https://tex.z-dn.net/?f=%20%28u-3%29%2A%282u%2B1%29%3D0%20)
(u-3)=0--------------> u=3
(2u+1)=0-------- 2u=-1------> u=-1/2-----> u=-0.5
IV. Rewrite your solutions to Part III by replacing u with sin x.
sin x=3--------> is not the solution (sin x can not be greater than 1)
sin x=-0.50------>is the solution
V. Solve the remaining equations for x, giving all solutions to the equation.
sin x=-0.50
if the sine is negative
then
x belong to the III or IV quadrant
we know that
sin 30°=0.50
so
the solution for the III quadrant is
x=180°+30°-------> x=210°
the solution for the IV quadrant is
x=360°-30°------> x=330°
