Question

How do you solve: 6 is greater than or equal to - 2/3d

Answer 1

6 ≥ -2/3 d
multiply both sides by -3/2
-9 ≤ d
Notice I flipped the sign at the end. Anytime you multiply or divide by a negative number always flip the sign.

Answer 2

thank you, but why do you multiply by -3/2 instead of -2/3

Answer 3

because I wanted to get rid of the -2/3 so I multiplied by its reciprocal.

Answer 4

oh okay thank

Answer 5

how would multiplying -2/3 by -3/2 look like

Answer 6

anytime you multiply by the reciprocal of a number you get 1
-2/3*-3/2 so multiply the numerators and denominators to get 6/6 (negative times negative is positive) this simplifies to 1
