Let A-10, 1, 2, 3, 4, 5,6), let B = 10, 1, 2, 3, 4, 5,6, 7,8), and let R be the relation from A to B given by "the greatest common divisor of a and b is 2." [Note: "greatest common divisor" is sometimes called "highest common factor"] List the elements of R.
Answers
Answer:
R = {(10,2), (10,4), (10,6), (10,8), (2,10), (2,2), (2,4), (2,6), (2,4), (4,10), (4,2), (4,6), (6,10), (6,2), (6,4), (6,8)}
Step-by-step explanation:
A = (10, 1, 2, 3, 4, 5, 6)
B = (10, 1, 2, 3, 4, 5, 6, 7, 8)
R is a relation and defined as
R: A→B
R: The greatest common divisor of a and b is 2
To find the elements of R we need to find pair from A and B respectively.
R = {(10,2), (10,4), (10,6), (10,8), (2,10), (2,2), (2,4), (2,6), (2,4), (4,10), (4,2), (4,6), (6,10), (6,2), (6,4), (6,8)}
Now, these pairs were found by picking one element from A and checking with elements of B if they have a gcd of 2. If yes, they fall under the defined relation.

Answer:
20.9 is the answer because To round 20.86 to the nearest tenth consider the hundredths’ value of 20.86, which is 6 and equal or more than 5. Therefore, the tenths value of 20.86 increases by 1 to 9. 20.86 rounded to the nearest tenth = 20.9

You may solve this problem in two ways:
If you solve the inequality explicitly (divide both sides by 4), you get
So, if has to be stricktly less than 4, you can only choose 1, 2 and 3 as answers.
Alternatively, you can plug in all of the values you're proposed and check if the inequality holds:
If , you have
, which is true.
If , you have
, which is true.
If , you have
, which is true.
If , you have
, which is false.
So, again, only 1, 2 and 3 are solutions.

To simplify this expression, you must follow PEMDAS.
3x(3+12÷3) parentheses first
3x(3+4) do the division
3x(7) addition inside of parentheses
21x multiplication
This means that Jay is incorrect in doing addition first.
I really hope this helps!

Final answer:
The greatest common divisor (GCD) of 22 and 99 is 11. Therefore, Miguel can make 11 equal packages where each package has 2 cans of regular soda and 9 cans of diet soda.
Explanation:
This problem is about finding the greatest common divisor (GCD) of two numbers, also known as the greatest common factor. The number of packages Miguel can make, and the amount of regular and diet soda in each, depend on the GCD of 22 (number of regular soda) and 99 (number of diet soda).
To find the GCD, you can use the Euclidean Algorithm. However, it is easily observed in this case that 22 and 99 can both be divided exactly by 11, hence, 11 is the greatest common divisor. This means Miguel can prepare 11 packages where each package contains 2 cans of regular soda and 9 cans of diet soda.
