I think it is the top cube.
15 books, because it asked for DIFFERENT books not the same. Just take the same book away from each individual child and add the rest and it equals 15.
If you were to combine all 6 of the triangles it should have formed a hexagon
Answer:
x=14
y=30
Step-by-step explanation:
5x+25=3x+53
5x=3x+28
2x=28
x=14
2y+35=95
2y=60
y=30
(I assumed all of the angles are equal, correct me if I'm wrong.)
No, it is not.
6= 2x3.
9= 3x3.
The lowest form is 2/3.
It is false.
