To determine which number from the set {6, 7, 8] makes the equation 54 ÷ x = 9 true, we can substitute each number into the equation and see which one makes the equation true.
1. If x = 6:
54 ÷ 6 = 9
9 = 9 (True)
2. If x = 7:
54 ÷ 7 = 9
7.714 ≈ 9 (Not True)
3. If x = 8:
54 ÷ 8 = 9
6.75 ≠ 9 (Not True)
Therefore, the number from the set {6, 7, 8} that makes the equation true is 6.
Use substitution to determine which number from the set {6, 7, 8] makes the equation 54 ÷ x = 9 true. (1 point)
