Answer:
The number of counties in state A are 70.
The number of counties in state B are 68.
Step-by-step explanation:
The number of counties in state A and the number of counties in state B are consecutive even integers whose sum is 138.
Let the two consecutive even integers be x and x+2.
As their sum is 138, we can denote this mathematically as :
[tex]x+x+2=138[/tex]
[tex]=> 2x+2=138[/tex]
[tex]=> 2x=138-2[/tex]
[tex]=> 2x=136[/tex]
Now, we get x = 68
And [tex]x+2=68+2[/tex] = 70
Hence, the two numbers are 68 and 70.
So, the number of counties in state A are 70.
The number of counties in state B are 68.
