The difference between the length and width of a rectangle is 7 cm. its perimeter is 50 cm. find the length and width of this rectangle.

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.

If the value of x increases by 5, how does the value of m(x + 3) change? a) it increases by 5m. b) it increases by 8m. c) it decreases by 5m. d) it decreases by 8m.

Solve 3x-18=2y and 5x-6y=6 by elimination show work
