Elena packed 48 cubes.
Each cube has an edge of 1 centimeter.
The number of layers that Elena can make depends on how each layer is arranged and depends on how many cubes are there in a layer.
Assume that each layer has only 1 cube, then there are 48 layers.
It would be 9 buddy. Negative divided by negative turns into positive. 45 divided by 5 is 9.
1 and 1/2 is the scale factor
3x-4y=12
4y=3x-12
y=(3x-12)/4
y=(3/4)x-3
