Answer: 
Step-by-step explanation:
A rectangular prism is a three-dimensional solid.
A rectangular prism has six faces (each one of these faces are rectangles), eight vertices and twelve edges.
You know that this rectangular prism has 5 layers and the volume of one of these layers is 18 cubic centimeters (
).
Assuming that all these layers are equal, the volume of this rectangular prism can be calculated with:
Where 
is the volume of one layer.
Substituting, you get:
If you add all of the numbers together the answer your going to get is 17+32+28 which equals 77
Answer: The answer is G
Step-by-step explanation:
If you don't see the stars, then the sky is not clear. This statement is equivalent to saying "If the sky is not clear, then you don't see the stars", because if you rearrange both statements you will find out that they are equivalent to each other.
Mark out all the words in each statement, you will discover that at the end you will have no word left on both side, its just as good as saying 1 - 1 = 0.
Answer:
40
Step-by-step explanation:
9a + 9b + 9c = 5
We want 72a
72a/9a = 8 so multiply the first equation by 8
8(9a + 9b + 9c) = 5*8
72a +72b +72c = 40
