C

Explanation

To find the range of values of x that satisfy the inequalities 5 + x ≤ 8 and 13 + x ≥ 7, we can solve each inequality separately and then find the overlapping range.1. Solving the first inequality, 5 + x ≤ 8:  Subtracting 5 from both sides, we have:  x ≤ 8 - 5  x ≤ 32. Solving the second inequality, 13 + x ≥ 7:  Subtracting 13 from both sides, we have:  x ≥ 7 - 13  x ≥ -6Now, let's find the overlapping range by considering both inequalities together:The range of values of x that satisfy both inequalities is the intersection of the ranges x ≤ 3 and x ≥ -6. This means that x must be greater than or equal to -6 and less than or equal to 3.Therefore, the range of values of x that satisfy the given inequalities is -6 ≤ x ≤ 3.
