The number of counties in state A and the number of counties in state B are consecutive even integers whose sum is 138 138. If s

ss7ja [257]

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 :

$x+x+2=138$

$=> 2x+2=138$

$=> 2x=138-2$

$=> 2x=136$

Now, we get x = 68

And $x+2=68+2$ = 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.

Prove that if a and b are nonzero integers, a divides b, and a b is odd, then a is odd.

hammer [34]

It is proved that the if a and b are nonzero integers, a divides b, and a b is odd, then a is odd.

According to the statement

we have to prove that the if a and b are nonzero integers, a divides b, and a b is odd, then a is odd.

And for this proof we use the contradiction

So,

Proof by contradiction is a common proof technique that is based on a very simple principle: something that leads to a contradiction can not be true, and if so, the opposite must be true.

So for this purpose,

Assume a is even, so a = 2k for some integer k. Now let a and b be integers such that a divides b and a + b is odd.

Since a divides b, b = an for integer n, and in turn b = 2nk, which means b is even and hence a + b is also even. But this contradicts our initial assumption, so a must be odd.

So, It is proved that the if a and b are nonzero integers, a divides b, and a b is odd, then a is odd.
