6x-3y=12

Step 1- move the 6x to the other side using the opposite operation (-6x)
-3y=12-6x

Step 2- divide everything by -3
y=-4+2x

Step 3- rearrange into the correct order (y-mx+b)
y=2x-4

Step A is wrong because the 12 wasn;t changed to the inverse or opposite operation (-12), while the others were changed.

Answer:6

Step-by-step explanation:

If we know that the formula of a rectangular prism is length * width * height, and we know the height and width are 7 and 9, the length is the only thing that is left. The volume is 378, and so now we have:

length * 7 * 9 = 378. Dividing the 9 and 7, we get 378/(9*7). The length is 6.

Crazy boy [7]

Answer:

Triangular pyramid and Rectangular prism

Step-by-step explanation:

There are several different uses of the formula V = BH. For example, we used the formula V = BH for a cylinder, a rectangular prism, and a triangular pyramid. But be careful! All of the elements in the formulas don't mean the same! I really hope this helps you a bit!
