(-3/5) / (7/6)....when dividing fractions, flip what u r dividing by, then multiply
-3/5 * 6/7 = - 18/35
1.5x=3
First you want to get x by itself so divide both sides by 1.5
3/1.5=2
x=2
The answer is a. Just check the work below to understand
D=546m. r=1.3m/sec. 546m=1.3m/sec(t).
546m divided by 1.3m/sec = t = 420 sec (the meters will cancel out, leaving the answer to just seconds).
420 seconds divided by 60sec/min = 7 minutes.
