The product of 9 and a number is 12 less than three times that number. What is the number?

1 answer:

5 0

So let me give you the answer with procedure so that you can understand it better:
Let x = Number

Product of 9 and Number:
9x 
is 12 less than 3 times that number. So: 
3x - 12 
Set them equal and solve for x like this:
9x = 3x - 12 
6x = -12 
x = -2
I hope this is very useful for you

I believe to answer this question you would simply divide by 5 for the dimensions to get the size of the scale drawing, and given it is a drawing I can only assume it would be measured in inches, so the answer in my mind would be 24 by 15 inches. I hope this helped, have a nice day! :)
