Answer:
7
Step-by-step explanation:
c.
the most that can be factored out is -1.5,
-1.5 * w = -1.5w
-1.5 * -5 = 7.5
-1.5w + 7.5, so it's
-1.5(w-5)
3x-y-2z=4. 2x+3y-4z=1
4x-7y-6z=-7. -x+6y+4z=11
- +. +. +. x+9y=12
____________.
-x +6y +4z=11.
In fraction, 144/100
Mixed number = 1 44/100
Simplest form = 144
