x=75
I believe it is the commutative property, hope this helps!
Answer:
46
Step-by-step explanation:
You have to do IVU+TUI=TUV
so... x+49+x+63=106
<span>2.607 x 10^13 dollars per person.
Avogadro's number is approximately 6.0221409x10^23.
So divide by the 231 million people. Giving
(6.0221409 x 10^23) / (231 x 10^6) = 0.02607 x 10^17
= 2.607 x 10^15 pennies
But we want dollars, so divide by 100
2.607 x 10^15 / 100 = 2.607 x 10^13 dollars</span>
