CONT.....

Answer 1

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
Part 1
a Define 2 variables to rep the amount of time ashley can spend on the two machines
b Write a system of 2 equations that describe the relationships between the amount of time ashley can spend on the 2 machines.
c. Solve the system of equations
d Interpret the solution

Answer 2

let's start by defining our variables for ashley

s = number of minutes on stair machine
r = number of minutes on rowing machine

using our two conditions, we have:

s + r = 40
and
s = 2r

solve the system for s and r

Answer 3

It would be 2r+r=40 then 3r=40, 40/3=answer
