Which symbol in place of the question mark makes the inequality 2x ? 20 true for the solutions 10, 11, and 12?(1 point)
The correct symbol is ≤ (less than or equal to).
2x ≤ 20 is true for x = 10, 11, and 12:
2(10) = 20
2(11) = 22
2(12) = 24
All of these values are less than or equal to 20, so the inequality holds.
