Solve the inequality.
fraction numerator negative c over denominator 2 end fraction less than negative 1.5

  1. c > -3
  2. c < -3
  3. c > 3
  4. c < 3

hintHint:

we have to remove -1/2 from c , how i can remove ? by multiplying by -2 both side.

The correct answer is: c > 3


    negative c over 2 less than negative 1.5
fraction numerator negative c over denominator 2 end fraction space cross times space minus 2 space greater than space minus 1.5 space cross times space minus 2 space space left parenthesis i n e q u a l i t y space s i g n space w i l l space c h a n g e space o n space m u l t i p l y i n g space b y space n e g a t i v e space n u m b e r
fraction numerator 2 c over denominator 2 end fraction space greater than space 3
c greater than 3
