A rail transport freight train also bound for New Orleans leaves Baton Rouge at 1;30 PM on the same day. The train travels at 25 MPH and the river barge travels at 10 MPH. ... the barge leaves at 9:00 am so that would be at 9 hours past midnight. the train leaves at 1:30 pm so that would be at 13.5 hours past midnight.
b.The additive inverse of −3 is +3, so 17 − (−3) = 20.
c.The additive inverse of −3 is −3, so 17 − (−3) = 14.
d. The additive inverse of −3 is +3, so 17 − (−3) = 14.
The answer to the question would be
B. The additive inverse of-3 is +3, so 17-(-3)=20 That's because if you do KCC (Keep Change Change )then you would get 17+3 add 3+17=20 that's easy
Answer: 20
Step-by-step explanation: -3 is +3, so 17- (-3) = 20
