Then subtract a*0 from both sides to get that a*0 = 0.

Secondly prove that a*(-c) = - a*c by a*(-c) + a*c = a*(-c+c) = a*0 = 0.

From this equation it follows that a*(-c) = - a*c from the definit...]]>

I can come up with two separate approaches, but not one that uses only the 6 axioms given and 4 theorems already proven. One approach I have uses the fact that "a x 0 = 0", and the other uses the fact that "-(a(-c)) = ac". The text...]]>

t = the number of days needed to finish The have d = 93 - 35 = 58 miles to finish. Since v = d/t we have 58/t = 2.9 t = 20 days. It will take 20 days more to finish the road. ]]>
