Question

p = 20 + 16 n The given equation relates the numbers p and n , where n is not equal to 0 and p &#62; 20 . Which equation correctly expresses n in terms of p ?

Accepted Answer

Choice D is correct. To express n in terms of p , the given equation must be solved for n . Subtracting 9 from both sides of the given equation yields p - 9 = 14 n . Since n is not equal to 0 , multiplying both sides of this equation by n yields p - 9 n = 14 . It's given that p > 9 , which means p - 9 is not equal to 0 . Therefore, dividing both sides of p - 9 n = 14 by p - 9 yields p - 9 n p - 9 = 14 p - 9 , or n = 14 p - 9 . Choice A is incorrect and may result from conceptual or calculation errors. Choice B is incorrect and may result from conceptual or calculation errors. Choice C is incorrect and may result from conceptual or calculation errors.
