Set up multiplication/division to cancel out units that you do not need for your final answer and introduce units that you do.
You want your answer in the form km/hr and you are starting with m/s so:
(12m/s)(km/1000m)(60s/min)(60min/hr)=43.2km/hr
The car is traveling at 43.2 kilometers per hour.
-9 < 6 -v < 9 . . . . two inequalities
-15 < -v < 3 . . . . . subtract 6
-3 < v < 15 . . . . . . multiply by -1
The simplest form of the expression is -10 + 8v + 32w
Given the expression
-10(-v+6w)-w-9(-3w-v)
First, we need to expand the given equation using the distributive law:
-10(-v+6w)-w-9(-3w-v)
= -10-v+6w-w-9(-3w)+9(v)
= -10-v+6w-w+27w+9v
Collect the like terms:
= -10 - v +9v + 6w - w+ 27w
= -10 + 8v + 32w
Hence the simplest form of the expression is -10 + 8v + 32w
