5. Kassidy earned a grade of 85% on her multiple-choice science final
that had a total of 150 problems. How many problems on the final
exam did Kassidy answer correctly?

its 127 or 128. if you round up its 127 if you round down its 128.

Step-by-step explanation:

you divide 127(8) by 150

You can consider lost yards as negative, and gaines yards as positive. So, if they lost 9 yards and then gained 9 yards, the expression is

-9+9=0

This means that the team is exactly where it started (which maked sense, because they lost exactly as much as they gained.

If they gained first and lost then, it wouldn't change a thing: you'd have

9-9=0

and so the team is always where it started.
