120

  • UsukiDoll
yup so now we have -np>120 we just need to divide when dividing both sides with a negative sign we need to switch the inequality signs
UsukiDoll
  • UsukiDoll
now we need just an n by itself... what can we divide to both sides to make that happen?

divide by p
UsukiDoll
  • UsukiDoll
yes we divide by p , but remember we want just positive n by itself so we need to divide both sides by -p and since we have a negative sign involved, the inequality sign gets switched.

oh ok
UsukiDoll
  • UsukiDoll
-np >120 \[n < \frac{120}{-p}\]
UsukiDoll
  • UsukiDoll
though negative signs in the denominator is frowned upon :( so just place it in the numerator/ \[n < \frac{-120}{p}\]

ok
UsukiDoll
