Answer:
Step-by-step explanation:
Refer to physics equation 
, where 
is angular velocity.
Angular velocity's SI unit is rad/s. Convert rev/min to rad/s:
Now substitute 
and 
into :
Answer:
No.
Step-by-step explanation:
Let's first and try to isolate x.
-2x < 5
(Divide by -2)
x > -5/2 ( < changes to > b/c it was divided by a negative)
x > -2.5
Since x is all values greater than -2.5, -6 is not within those bounds.
Thus, -6 is not a solution to the inequality.
