Sid went scuba diving. He rose 15 feet from his original position. He then descended, going down in 3 increments of 7 feet each. His final position was 10 feet below sea level. Find Sid’s original position.

Respuesta :

Answer:

16

Step-by-step explanation:

I started at zero, added 15, we get 15, I then subtracted 21, since 3 times 7 is 21. I get -6. If instead made my base number 6, and then did all this, I would get zero. I would then add 10 to the base number of six, making my base number 16. Doing this process all over again, you indeed find it to be 10. 16 + 15 = 31. 31- 21 = 10.
