Final answer:
To isolate X in the equation A=CDX, divide both sides of the equation by (CD) to get X alone. If A is halved while C and D remain constant, the value of X does not change.
Step-by-step explanation:
To isolate X in the equation A=CDX, we need to rearrange the equation. Divide both sides of the equation by (CD) to get X alone. So, the rearranged equation would be X = A / (CD).
Substituting the given values of C=5.00, D=9.00, and A=3.00 into the equation, we have:
X = 3.00 / (5.00 * 9.00)
Calculating this expression gives us X = 0.0667.
Now, if A is halved while C and D remain constant, the value of X will remain unchanged. So, the answer is (c) The value of X does not change.
