Question 8985: Hi, could you please help me on a problem that I have. I do not need to solve this problem, I just need to put it into an equation. This is the problem: The height of a tower is three times the height of a certain building. If the tower is 50 m taller than the building, how tall is the tower?
I tried to work out the problem: I used b for my variable. Then I used 3b for the tower height, and b for the building height (I'm in the beginning of Algebra 1, so we are suppose to use only 1 variable).
Then I put together this equation: 3b - b = 50 m. Could you please tell me if this is right, and also add how you get it? Thank you so much!!
