Question

Use substitution to determine which number from the set {6, 7, 8} makes the equation 54÷x=9 true.(1 poin

Answer 1

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 results in the equation being true.

1. Substitute x = 6:
54 ÷ 6 = 9
9 = 9
This is true.

2. Substitute x = 7:
54 ÷ 7 = 9
7.71 does not equal 9
This is false.

3. Substitute x = 8:
54 ÷ 8 = 9
6.75 does not equal 9
This is false.

Therefore, the number from the set {6, 7, 8} that makes the equation 54÷x=9 true is x = 6.
