!!SOLVE!! Miguel also uses the stair machine and the rowing machine at the gym for an exercise program. His trainer wants him on an exercise program that meets these three conditions: 1) Miguel will spend at most 60 minutes working out at the gym. 2) Miguel will exercise for at least 30 minutes, dividing his time between the stair machine and the rowing machine. 3) Miguel will spend at least twice as much time on the stair machine as on the rowing machine, Questions A. Define two variables to represent the amounts of time miguel can spend on the 2 exercise machines. B. Write a system of 3..

    so... im not great at these, but here we go: y = time on stair machine x = time on rowing machine 1st inequality x+y must be less than 60? x+y < 60 is that right?

    Well it would be \[ x+y \le 60\]

    true, greater than or equal to, my bad ummm... k, so 2nd 2. Miguel will exercise for at least 30 minutes, dividing his time between the stair machine and the rowing machine. so x + y must be greater than 30 2nd eqn : 30<or= x+y ?

    3) Miguel will spend at least twice as much time on the stair machine as on the rowing machine, so if y = time on stair machine x = time on rowing machine then 3rd eqn is something like: y>or=2x ?
