7 m = 5 n + p The given equation relates the positive numbers m , n , and p

Question

7 m = 5 n + p The given equation relates the positive numbers m , n , and p . Which equation correctly gives n in terms of m and p ?

Accepted Answer

Choice B is correct. It's given that the equation 7 m = 5 n + p relates the positive numbers m , n , and p . Dividing both sides of the given equation by 5 yields 7 m 5 = n + p . Subtracting p from both sides of this equation yields 7 m 5 - p = n , or n = 7 m 5 - p . It follows that the equation n = 7 m 5 - p correctly gives n in terms of m and p . Choice A is incorrect and may result from conceptual or calculation errors. Choice C is incorrect and may result from conceptual or calculation errors. Choice D is incorrect and may result from conceptual or calculation errors.
