Answer:
10a = 30
Step-by-step explanation:
By using elimination:
4a + 2z = 10
-2(3a + z) = -2(-10)
4a + 2z = 10
6a - 2z = 20
2z and -2z cancel out
10a = 30
a = 3
They are asking for 10a, so 10 (3) = 30.
You can just overall divide 100 from 25 to get a percentage because you're trying to find the percentage of captown only but per se if you were to find various cities in Maltania than you can just divide 100 by the percent of the population.
Answer:
Let a and b integers and suppose that are even numbers. Then, exist integers k and m such that
and
.
Then,

Since, k and m are integers then n=k+m is an integer. Then, since a + b is of the form 2 by an integer n, then a + b is an even number.
