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

Answer 1

We can start by assuming that x is one of the numbers from the set {6, 7, 8}. Then, we can substitute each number into the equation and see which one makes it true.

Let's start with x=6:
54 ÷ 6 = 9
9 = 9
This is true, so x=6 is a possible solution.

Now let's try x=7:
54 ÷ 7 ≠ 9
This is not true, so x=7 is not a solution.

Finally, let's try x=8:
54 ÷ 8 ≠ 9
This is also not true, so x=8 is not a solution either.

Therefore, the only number that makes the equation 54÷x=9 true is x=6.

Answer 2

or ...

by just knowing from your multiplication table that 9 x 6 = 54, so
54 ÷ 6 = 9

Answer 3

so is it 9 or 6
