H = 9
4h - 11 = h + 16
subtract h from both side and add 11 to both
3h = 27
divide both sides by three
h= 9
It is 35% because you need to divide 21 out of 100 then multiply the answer you get by 7

Step-by-step explanation:
its just moving the point.
3.72 x 10^6 you moved the point 6 times to the left so its positive.
5 x 10^-11 moved it 11 times to the right so its negative
Both are the same because the first line is going by ×2 so the missing number would be 22. The second line is going by +1 so 21+1=22. (Hope this will prove your friend wrong :3)
