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 :
Now, we get x = 68
And 
= 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.
Answer:
the answer is A.

From the given problem, it says show how to make a ten to solve 13-7.
Subtracting 13 to 7 gets 6. In order to get a 10, subtract 10 by 6. 10-6 = 4.
So, you need to add 4 in order to make a ten.
Disclaimer: What do you by make a ten to solve 13-7?
The term with degree 4 is
.
The coefficient of the term is the constant number that is being multiplied with the variable of the term. In case of
, the variable is x raised to the power 4 and the constant term that is being multiplied to the variable is 5.
So the coefficient of of term of degree 4 is 5.
Thus correct answer is option D
Answer:
300 dimes and 120 quarters
Step-by-step explanation:
Let x be the number of dimes and y be the number of quarters Travis has. Travis has $60 (6000 cents) in dimes and quarters, then
If he could switch the numbers of dimes with the number of quarter, he would have y dimes and x quarters. In total this amount of money is $87 (8700 cents), then
