\(x + 2y > 8\)

Quantity A

Quantity B

\(2x + 4y\)

\(20\)

A) Quantity A is greater. B) Quantity B is greater. C) The two quantities are equal. D) The relationship cannot be determined from the information given.

Given eqn \(x + 2y > 8\) Multiply both sides by \(2\) we get, \(2x + 4y > 16\) We can derive Qty A is greater than \(16\) so Qty A could be \(17,18,19,20,21\) and so on Qty B is\(20\) So If qty A is \(20\) then the ans is c however qty A could be \(17\) and ans would be B option D

A) Quantity A is greater. B) Quantity B is greater. C) The two quantities are equal. D) The relationship cannot be determined from the information given.

GIVEN: x + 2y > 8 Multiply both sides by 2 to get: 2x + 4y > 16 So, we know that 2x + 4y evaluates to be some number greater than 16

Now take: Quantity A: 2x + 4y Quantity B: 20

And replace 2x + 4y to get: Quantity A: some number greater than 16 Quantity B: 20

As we can see, Quantity A could be LESS THAN 20, GREATER THAN 20, or even EQUAL TO 20.

Answer: D

answer: D x+2y > 8 So 2 * (x + 2y) > 16 So 2 * (x + 2y) can be even bigger than 20. A > B 2 * (x + 2y) can be between 16 and 20, A < B So D is answer. _________________
