Question

Please help with 29 and 30

Answer 1

Since this is an inequality, we must simplify the right side to compare to 18.

18 $\geq$ -8(6n-8) + 7((3n+5)
18 $\geq$ -48n + 64 + 21n + 35
18 $\geq$ -27n + 99
-81 $\geq$ -27n
3 $\geq$ n

Since 'n' is less than or equal to 3, you would have a solid dot on the 3 with a line going to the left.
