6.4 is the answer you are looking for! Hope that helps :))
Number 7 is 111 because they are alternate interior and 8 is 90
8:15 am is the answer because if u add up all of the timings it will become an hour and a half
And when u minus an hour and a half from 10:45 u get 8:15
She added the numerators
instead of multiplying them
you should also simplify the final answer
the correct answer would be -3 1/8 or -25/8 as an improper fraction.
