Answer:
16a^2+5
Step-by-step explanation:
None of these are correct. the answer is 6 hours, because if the the train is traveling at 30m/h and the distance = 180m than your equation is 30m/180
You need to put the 15 over 1 and multiply 6 by 3 to get 18, which would be added to 2 to get 20/3, which you flip in order to get 3/20. You multiply the 15 by the 3 and the 1 by the 20 to get 45/20. You then simplify to get 2 1/4
Well, if he walked one and three fourths miles five times, all you have to do is multiply one and three fourths and five to get your answer.
