Assuming that the triangles are congruent, you can just look at the parts on each triangle to find the parts on the other triangle. The answers are yes, yes, and no. The triangles are obviously not drawn to scale, so just remember to never rely on it being so.
The line plot smallest number always goes first biggest number goes last
X-y=3=>x=3+y
X+2y=-6
=========
3+y+2y=-6
3+3y=-6
3y=-6-3
3y=-9
y=-3
X+2y=-6
X+2(-3)=-6
X-6=-6
X=0
432 million, 540 times .20 equals 108, subtract 108 from 540 and you get your answer
Yes, 1/4 of 8 is equal to two.
1/4x8=2
Hope this helps! :)
