Question

Solve the inequality. –2w < –18 w < –16 w < 9 w > 9 w > –16

Answer 1

-2w < -18     change the signs

2w > 18     divide both sides by 2

w > 9

Answer 2

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.
