Answer:
0=3 0=-6
Step-by-step explanation:
If Keith is represented by x, and Joe is three less than Keith, Troy is represented by x-3.
Then, we know that Joe exercises for twice the amount of time as Troy, we multiply the expression for Joe by two.
Keith = x
Troy = x-3
Joe = 2(x-3)
2/5 + 1/2 = 0.9
0.9 in fraction form is 9/10!
Hope this helps!
