Answer:
The first question would likely be y=10.
The second question would likely be x=20.
Answer:
Anything
Step-by-step explanation:
5n - 10 = 5n - 10
It doesn't matter what you put in for n, the equality can never be anything but an equality.
Suppose n = 10,000,000
Then 5*10,000,000 - 10 = 5*10,000,000
Since Anna is either grouping them as single rock or as group of 10, we need to find the maximum number of groups of 10 as follows: 38/10 = 3.8
This means that Anna can make maximum 3 groups of 10 rocks.
Based on this, the different ways to group the rocks are as follows:
- 3 groups of 10 and 8 (which are calculated as: 38-30) single rocks
- 2 groups of 10 and 18 (which are calculated as: 38-20) single rocks
- 1 group of 10 and 28 (which are calculated as: 38-10) single rocks
- 0 group of 10 and 38 (which are calculated as: 38-0) single rocks
Speed is decreasing by 5 and position is -1
