Answer to Problem 7WE
The equation which gives the correct translation of the statement is
Explanation of Solution
Given Information: The statement “Eleven less than twice n is seven more than n ” and two possible expressions which are to be checked for translation.
The given statement represents a mathematic expression separated by an equality sign which can be decoded as follows.
(1)Considering left-hand side of the expression, it consists of difference between two numbers one being twice of number n and other being 11. This can be represented symbolically as
(2) The right-hand side of the expression consists of seven more than n which denotes the sum of number n and 7. This can be represented symbolically as
Thus, the final expression is given by,
Based on the given options the option a. gives the expression
