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.
