3x-16=2x-7. Add 16 to both sides to get 3x=2x+9. Then subtract 2x on both sides to get x=9
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.
