Answer explanation

Choice B is correct. It’s given that the minimum value of x is 12 less than 6 times another number n . Therefore, the possible values of x are all greater than or equal to the value of 12 less than 6 times n . The value of 6 times n is given by the expression 6 n . The value of 12 less than 6 n is given by the expression 6 n - 12 . Therefore, the possible values of x are all greater than or equal to 6 n - 12 . This can be shown by the inequality xe6n-12.

Choice A is incorrect. This inequality shows the possible values of x if the maximum, not the minimum, value of x is 12 less than 6 times n .

Choice C is incorrect. This inequality shows the possible values of x if the maximum, not the minimum, value of x is 6 times n less than 12 , not 12 less than 6 times n .

Choice D is incorrect. This inequality shows the possible values of x if the minimum value of x is 6  times n  less than 12 , not 12 less than 6 times n .
