Answer: n=-5

Step-by-step explanation:

distribute: 0.6(10n+25)=10+5n 0.6(10n)= 6n 0.6(25)=15 so then you put the problem together again... 6n+15=10+5n then you cancel out the n variable... 10-15=-5 6n=-5+5n 6n-5n=1n 1n=-5 -5/1 n=-5

Aidan writes numbers on his ten fingers as 5, 7, 9, 11, 13, 15, 16, 19, 22, 23. What is the probability of picking an even numbe

faltersainse [42]

It would be 2/10, or 1/5, since two out of the 10 numbers are even. 2/10 simplifies to 1/5, since there is 1 for every 5 numbers.

We could turn this into a percentage by dividing 1 by 5, which gives us 0.2. Then we can multiply by 100 to get 20.

So, our probability of choosing an even number is:
2/10
OR
1/5
OR
20%

Hope I could help!
