A small plane took off from Whitehorse to inspect a wildfire in the wilderness 255 kilometers away. Flying into the wind on the way out to the fire, the trip took 1.7 hours. Flying with the wind at its back, the plane only took 1.5 hours to return back to Whitehorse when it was done inspecting the fire. Determine the wind speed that day. a) Define the variables. b) Solve the problem.​

Three numbers x, y, and z are in the ratio 2: 7: 8. if 12 is subtracted from y, then three numbers form a geometric sequence (in the order x, y–12, z). find x, y, and z. there are 2 sets.

Three students, javier, sam, and corrine, participated in a fundraiser where people donated a certain amount of money per lap that the student ran. each student also had some initial donations that were collected before the run. the equations that represent each student's total donation, y, based on the number of laps ran, x, is shown below. match each equation with the correct rate of change for that student.
