Use substitution to determine which number from the set {6, 7, 8} makes the equation 54 divided by x = 9 true.

Answer 1

By substituting each number from the set {6, 7, 8} into the equation 54 divided by x = 9, we can determine which number makes the equation true:

For x = 6: 54 divided by 6 = 9. 54/6 = 9, so x=6 makes the equation true.

For x = 7: 54 divided by 7 = 7.71, which is not equal to 9. So, x=7 does not make the equation true.

For x = 8: 54 divided by 8 = 6.75, which is not equal to 9. So, x=8 does not make the equation true.

Therefore, the number 6 from the set {6, 7, 8} makes the equation 54 divided by x = 9 true.
