Answer: The required volume is 390 mm³.
Step-by-step explanation: Given that the stack on the left is made up of 15 pennies, and the stack on the right is also made up of 15 pennies. The volume of the stack of pennies on the left is 390 mm³.
we are to find the volume of the stack of pennies on the right in cubic millimeters.
The number of pennies on the left and right are same, equal to 15.
Also, the volume of the stack of pennies on the left is 390 mm³.
Since the number of pennies on the right and left are equal, so the volume of the stack on the right and left are also equal.
Therefore, the volume of the stack of pennies on the right is 390 mm³.
Thus, the required volume is 390 mm³.
Answer:
the answer is 11
Step-by-step explanation:

There are many ways of solving a system of equation, a very used one is by elimination of variables, which consists in eliminating one of the variables by combining the equations.
Let's do the following combination: (eq 1) + (eq 2)
This means that we add each term vertically:
⇒
When I said "add vertically" means that you add the first term of the first equation with the first term of the second equation. The second term of the first equation with the second term of the second equations, and so on.
This allowed us to remove the "y" temporarily so we can get a linear one-variable equation we can easily solve:
Now that we know the value of "x", we can plug it in any of the starting equations and get "y":
Therefore, our answer looks like this:
