Start with the formula D = A BC .
Divide both sides by A B to isolate C : A B D = A B A BC .
Simplify the equation: C = A B D .
The correct formula for C is C = D ÷ A B .
Explanation
Understanding the Problem We are given the formula D = A BC and we want to find the formula for C . This involves algebraic manipulation to isolate C on one side of the equation.
Isolating C To isolate C , we need to divide both sides of the equation by A B . This gives us: A B D = A B A BC
Simplifying the Equation Now, we simplify the equation. On the right side, A B in the numerator and denominator cancel out, leaving us with: A B D = C Thus, C = A B D .
Selecting the Correct Option Comparing our result with the given options, we see that option B, C = D ÷ A B , matches our derived formula.
Examples
In physics, if you know the total displacement D of an object, and you know the average velocity A and the time B it took, you can find the acceleration C assuming constant acceleration using the formula D = A BC . Rearranging this formula to solve for C allows you to calculate the acceleration directly.
To derive the formula for C from D = A BC , we isolated C by dividing both sides by A B , resulting in the equation C = D ÷ A B . The correct choice among the options provided is B. Thus, C = D ÷ A B represents the relationship we are looking for.
