Answer:
16 days or 15.5 I'm not sure what if the question wants exact answer or rounded to how many full days it will take
answer: i don't know what that is
No because when you plug in the ordered pair to either equation it doesn’t work. Y=2x+14 would go to 11=2(4)+14 and you would get 11=22 which is wrong. Again with y=3x-5 would be 11=3(4)-5; 11=7 which is wrong again.
