The height of a building is proportional to the number of floors. The figure shows the height of a building with 8 floors. H=112. What is the ratio of the height of the building to the number floors? What is the unit rate?how many feet is each floor of the building?

-3(b-8)-5=9(b+2)+1

distribute

-3b+24-5=9b+18+1

add/ subtract

-3b+20=9b+19

20-19= 1

-3b+1=9b

9b+3b= 12b

1=12b

1 divided by 12 = 1/12

answer: 1/12 = b

this would be 35. 35 + 5 = 40. you take the known constant and subtract by the answer of the equation and you get y.
