The symbol that makes the inequality 2x ? 20 true for the solutions 10, 11, and 12 is ≤ (less than or equal to).
Therefore, the correct symbol to add is ≤.

Apologies for the confusion. Let's reevaluate the inequality using the solutions.
When x = 10:
2(10) = 20, which is equal to 20. So, 2x ? 20 can be true with the symbol ≤.
When x = 11:
2(11) = 22, which is not less than 20. So, 2x ? 20 is false for x = 11 with the symbol ≤.
When x = 12:
2(12) = 24, which is not less than 20. So, 2x ? 20 is false for x = 12 with the symbol ≤.
Based on the values tested, the correct symbol in place of the question mark that makes the inequality 2x ? 20 true for the solutions 10, 11, and 12 is ≥ (greater than or equal to).
Therefore, the correct symbol to add is ≥.
What number is not part of the solution set for z5≠7 ?(1 point)
To determine which number is not part of the solution set for the inequality z5 ≠ 7, we need to solve for z.
The inequality z5 ≠ 7 can be re-written as z ≠ 7/5.
Therefore, the number 7/5 is not part of the solution set for the inequality z5 ≠ 7.
What number is not part of the solution set for z/5≠7 ?(1 point)
To determine which number is not part of the solution set for the inequality z/5 ≠ 7, we need to solve for z.
The inequality z/5 ≠ 7 can be re-written as z ≠ 7 * 5.
Therefore, the number 35 is not part of the solution set for the inequality z/5 ≠ 7.
If the representation of an inequality on a number line features a hollow circle with an arrow pointing leftward, what symbol would be used in the inequality itself?

If the representation on a number line features a hollow circle with an arrow pointing leftward, it indicates an open circle on a number line, representing a strict inequality. In this case, the symbol that would be used in the inequality itself is < (less than).
