Solve the inequality. 42 < –6d A. d < –7 B. d < 36 C. d > –7 D. d < –48

OpenStudy (anonymous):

You need to divide both sides by (-6)... but you also need to remember that with inequalities, when you multiply or divide by a negative number, you have to reverse the direction of the inequality.

so C

close, but not quite... Original problem: 42 < –6d Divide each side by (-6) and flip the inequality: 42 / (-6) > (-6d)/(-6) then simplify by reducing the fractions... -7 > d or turned the other way... d < -7
