Answer: 0.06 litre or 60 ml
Step-by-step explanation:
Given: The capacity of glass tank= 26 liter
If he add 20.9 liters of water after 85 marbles to fill it completely, then
The volume of 85 marbles= 
Since, the marbles have same volume.
∴ Volume of each marble= 
⇒ Volume of each marble=
In milliliters, Volume of each marble=
The first statement is true, because the two negative signs cancel each other out. However, the second is false because any time you multiply a positive number by a negative number the product is always negative. Therefore 4x-6=-24
