Answer: The third option, w > 9

Step-by-step explanation: It is kinda weird written, but let's try to solve it:

I guess that the inequality is: –2w < –18

and the options are:

w < –16

w < 9

w > 9

w > –16

the inequality says:

–2w < –18

first, we can multiply by -1, this changes the direction of the "lower than" symbol.

2w > 18

now we can divide both sides by 2, in order to isolate w.

w > 18/2 = 9

then we have that w >9.
