7. Baloney! The computer was wrong. Your "teacher" is not a real teacher if s/he does not explain it.

I've seen many wrong computer answers on Jiskha.

Also if only 1 out of 96 gets a problem correct, there is something wrong with the problem.

10. d = 1.5(3.6+4.2) = 11.7 miles.

Do your teacher know how to solve the problem?

Can she get the opinion of another math teacher at the school?
