= p (- k)/(4j +9) The given equation relates the distinct positive numbers p, k, and j. Which equation correctly 4j +9 expresses in terms of p and k? 4j +9 =
Correct answer: A (parsed from the explanation — this source omits an answer key for this item)
Explanation
4 +9 Choice A is correct. To express j in terms of p and k, the given equation 4 +9 4 +9 must be solved for j . Since it’s given that j is a positive number, j is not 4 +9 equal to zero. Therefore, multiplying both sides of the given equation by j 4 +9 = yields the equivalent equation p^ j h k. Since it’s given that p is a positive number, p is not equal to zero. Therefore, dividing each side of the equation 4 +9 = 4 +9=k p^ j h k by p yields the equivalent equation j . p = 4 j +9 Choice B is incorrect. This equation is equivalent to p . Choice C is incorrect. = -4 -9 k This equation is equivalent to p k j . Choice D is incorrect. This equation is = 4 +9 equivalent to p k^ j h.
