Answer: The solution to the inequality is x is less than or equal to 4. We can write it in interval notation as (-∞, 4].
Step-by-step explanation: To solve the inequality 1/2x + 8 ≤ 10, we need to isolate the variable x on one side of the inequality sign.
Subtracting 8 from both sides, we get:
1/2x ≤ 2
To isolate x, we need to multiply both sides of the inequality by 2:
x ≤ 4
