Quantity A: 7w-4 Quantity B: 2w+5 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.
Quantity A: 7w-4 Quantity B: 2w+5 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.
w>1
Quantity A: 7w-4
Quantity B: 2w+5
7w-4 ? 2w+5
collect like terms
7w-2w ? 5+4
5w ? 9
w ? 9/5
w ? 1.8
Lets assume that w=1.3, it means that w<1.8
but if w=1.9, it means w>1.8
Therefore, we can't conclude which is bigger between the 2 quantities.
Answer: The relationship cannot be determined from the information given (D)
