Chapter 41, Problem 15A
Express each ofthe word problems in Exercises 7 through 19 as equations. Let the unknown number equal x and by logical reasoning solve for the value of the unknown. Check the equation by comparing it to the word problem. Does the equation state mathematically what the problem states in words? Check whether the equation is balanced by substituting the value of the unknown in the equation
Sixty divided by the product of 3 and a number equals 4. Find the number.
