Eileen drove for 85 minutes. this is 21 more minutes than one third the number of minutes ethan drove. how do i put this into an equation?

(a) solve h+2/6 = h-3/4(b) solve the following simultaneous equations. 2x = y + 66x - 2y = 13x = ? y = ?

1. a right triangle is graphed on a coordinate plane. find the length of the hypotenuse. round your answer to the nearest tenth. 2. use the angle relationship in the figure below to solve for the value of x. assume that lines a and b are parallel and line c is a transversal.

Look at arnold's attempt to solve the equation for b: 3b = 12 b = 3 · 12 b = 36 describe the mistake that arnold made.
