Question

Exact answer please.

Answer 1

Answer:

d ≥ - 21

Step-by-step explanation:

$\frac{6-d}{9}$ ≤ 3 ( multiply both sides by 9 to clear the fraction )

6 - d ≤ 27 ( subtract 6 from both sides )

- d ≤ 21

multiply both sides by - 1, reversing the symbol as a result of multiplying by a negative quantity.

d ≥ - 21
