Question

-1.5 d equal or greater than 9

Answer 1

The inequality -1.5d ≥ 9 can be solved by dividing both sides of the inequality by -1.5. However, when we divide or multiply both sides of an inequality by a negative number, the inequality sign is reversed. So we have to flip the inequality symbol.

Thus, when we divide both sides by -1.5, we get:

d ≤ 9 / -1.5

Simplifying, we have:

d ≤ -6

Therefore, d is less than or equal to -6.
