Final answer:
To solve for X, divide Q by J using the provided values (98 and 2.333), which results in X being approximately 42, corresponding to option (a).
Step-by-step explanation:
To solve for X given the equation Q = XJ, with Q = 98 and J = 2.333, you want to isolate X on one side of the equation. This can be done by dividing both sides of the equation by J:
Q / J = X
Substitute the known values for Q and J:
98 / 2.333 = X
Calculating this gives:
98 / 2.333 ≈ 42
Therefore, X = 42, which corresponds to option (a), exemplifying how to isolate and calculate the unknown variable by applying known values within a simple equation to ascertain the solution.
