Your answer should be B.
x+2y=8
It is False because negative as good to the left
4 (20/12) ÷ (4-3)
Simplify
4 (10/6) ÷ 1
Anything divided by one is itself
4 (10/6)
which would give you 40/6, which is better kept as a fraction because of recurring numbers
Hope this helped
The horizontal value in a pair of coordinates: how far along the point is. The X Coordinate is always written first in an ordered pair of coordinates (x,y), such as (12,5). In this example, the value "12" is the X Coordinate. Also called "Abscissa"
