The percentage would be about 64%
Known that,
x = z
Also known that,
x + y = 10
Substituting value of x,
z + y = 10
Hence, proved.
I’m not positive about this but I believe 6
x+y=18897
x=y+673
2y+673 = 18897
2y = 18224
y= 9112
x = 9112+673 = 9785
9112 + 9785 = 18897
so one country is 9112 and the second country is 9785
Scientific notation is another way to write a number. In scientific notation, the letter E is used to mean "10 to the power of." For example, 1.314E+1 means 1.314 * 101 which is 13.14 .
