Answer 1

Let's say the number is x.

The sum of a number and 8 is x + 8.

The product of 9 and the sum of a number and 8 is 9(x + 8).

Therefore, we have the equation 9(x + 8) = 180.

Expanding the equation, we get 9x + 72 = 180.

Subtracting 72 from both sides of the equation, we get 9x = 108.

Dividing both sides of the equation by 9, we get x = 12.

Therefore, the number is 12.
