Answer:
x=142, y=-360. (142, -360).
Step-by-step explanation:
5x+2y=-10
3x+y=66
----------------
5x+2y=-10
-2(3x+y)=-2*66
-----------------------
5x+2y=-10
-6x-2y=-132
-------------------
-x=-142
x=142
3(142)+y=66
426+y=66
y=66-426
y=-360

Step-by-step explanation:
None of the above I believe
Break down the figure into 2 separate rectangular solid and find each volume and sum it.
<u>Volume of smaller step:</u> The volume of any rectangular solid is given by,

So we have 
<u>Volume of larger step:</u> The only dimension that is different than the smaller step is of the height, which is 6. So we have,

Hence, the volume of the whole figure, in cubic inches, is
