GIVEN: x/y = 2/3
Cross multiply to get: 3x = 2y
Also given: x + y = 15
If x + y = 15, then we can write: x = 15 - y
Now take 3x = 2y and replace x with 15 - y
We get: 3(15 - y) = 2y
Expand: 45 - 3y = 2y
Add 3y to both sides: 45 = 5y
Solve: y = 9
Which of the following is greater than y ?
In other words, which of the following is greater than 9?
ASIDE:
√64 = 8
√81 = 9
√100 = 10
√121 = 11
√144 = 12
Since √81 = 9, we're looking for all answer choices that are GREATER THAN √81
Answer: B, C, D, E
