Answer:
15
Step-by-step explanation:
dont change the 10 and whats 8 + 7
If you are talking about any number then.....
imagine a mountain, any number less than 5 is only the left and any number greater than 5 is on the right
Here, for example, let's try 13
look at 13 on the pyramid .... since it's not a the top of the mountain so it falls back down to 10... it rounds down to 10
Now let's try 18 ...hmmm.... 18 is not at the top either so it falls as well. It falls down to 20 it rounds up to 20
how about 15 u might be asking...it is at the top...15 is a little different ...make sure no one is looking and push it off the right side and falls to 20. Also rounding up to 20
5
4 6
3 7
2 8
1 9
0 10
What you do is 8 x 8 x 8 and cube your number
=512
You’d add 65+79 to get 144 then subtract that from 180 and get 36 so X would be 36 :) hope this helped!
1999 price = 11900
it depreciates 13%
year 2000 cost = 11900 - 1547 = 10353
it depreciates 13%
year 2001 cost = 10353 - 1345.89 = 9007.11
it depreciates 13%
year 2002 cost = 9007.11 - 1170.92 = 7836.19
pls mark as brainliest
