Answer:
Markus has 6 marbles in each bag.
Step-by-step explanation:
Markus has 18 marbles and 3 bags
If you divide 18 marbles by 3 bags that would be 6 marbles in each bag.
This will be 18.39, 6 is higher than 5, so the 8 is going higher so it's a 9 and you will get 18.39
Isolate the w. Note the equal sign. What you do to one side, you do to the other.
Add 3π to both sides
- 3π (+3π) + w = 2π (+3π)
w = 2π + (3π)
w = 5π
w = 5π is your answer
hope this helps
If the initial time was 60 seconds and 18 seconds have passed,

There would be 42 seconds left.
