Answer:
I think the answer you're looking for is -49.05
(longer version: -49.0504)
The answer is (2,1). 2*2=4 and 9*1=9. 9+4=13
-4(-5-b)=1/3(b+16) Multiply both sides by 3 to get rid of the fraction
-12(-5-b)=b+16 distribute the -12 to get rid of the parenthesis
60+12b=b+16 get the b on the left side and non b values to the right side
11b=-44 solve for b
b=-44/11 simplify the fraction
b=-4
3/5(t+18)=-3(2-t) multiply both sides by 5/3 to get rid of thefraction
t+18=-5(2-t) distribute the -5 to get rid of the parenthises
t+18=-10+5t get the t to the left side and non t values to the right
-4t=-28 solve for t
t=7
Not all 30-story buildings are the same height. Depends on how tall the ceiling is on each floor. But usually it is around 300 feet
