Find the A union B
A={2,4,5,8,9} and B={0,1,6,7}

Point $(x, y)$ is randomly picked from the rectangular region with vertices at $(0,,,2010),$ and $(0,2010)$. what is the probability that $x > 7y$? express your answer as a common fraction.

7x+8y=-18, 4x-9y=-3 solve the system of equations

The angle of a triangle are given as 6x,(x-3), and (3x+7). find x then find the measures of the angles
