Answer 1

\(\bf{9+3n≥6~or~5n<25}\)

Answer 2

let's do the simple one first
\(\bf{5n<25}\)

Answer 3

divide \(\dfrac{25}{5}\)

Answer 4

n< 5

Answer 5

correct
b and c are out

Answer 6

now \(\bf{9+3n≥6}\)
subtract 6 - 9

Answer 7

3n ≥ -3

Answer 8

correct
now divide \(\bf{\dfrac{-3}{3}}\)

Answer 9

-1
