Final answer:
To solve for 'w' in A = w when A = 28 and w = 2, it seems we actually should have an operation in the equation, possibly a typo. If so, we would divide 28 by 2 to isolate and solve for 'w', resulting in w = 14. Otherwise, with A = w, if A = 28 then w also equals 28 directly.
Step-by-step explanation:
To solve for 'w' using the formula A = w, when A = 28 and w = 2, we must identify the correct operation to isolate 'w'. The given formula suggests that 'A' is the product of some value 'w', but as the question states that w = 2, it seems like we might be dealing with a proportional situation or a simple equation to solve for 'A'. However, based on the question, if it is indeed A = w and we need to find the value of 'w' equivalent to A, and we have A = 28, it would imply that w = 28 directly, without the need for any mathematical operations. But if the original intention of the question was to suggest a multiplication operation (A = w * a certain value), and we need to find 'w', it might be a typo, and it should be solved as follows:
If the actual equation is A = w * 2 and A = 28, to solve for 'w', we would divide 28 by 2, which would give us:
w = 28 / 2
w = 14
So the correct answer is (a) Divide 28 by 2.
