Answer:
B. 1/4(x-5) = 13
Explanation:
You want to know which number sentence has one solution.
Inequality
Typically, an inequality has an infinite set of solutions. The inequalities here are linear inequalities in one variable, so will have an infinite solution set consisting of numbers greater than, or less than, some boundary value.
Equation
If the equation can be arranged to be in general form, ax +b = 0, where a ≠ 0, then it will have exactly one solution: x = -b/a.
The set of number sentences contains exactly one equation. That is the number sentence that has exactly one solution:
B. 1/4(x-5) = 13
