Use proportions to find the height of the building-
\frac{x}{1}=\frac{8}{.2}
The x is the height of the building.
It is over 1 (the height of the other building) because both are heights.
Similar triangles are in proportion so the other fraction is in proportion to it.
Cross multiply(x times .2) (8 times 1).  You will get this equation-
.2x=8
Solve for x by dividing-
x=40
Since this was done in meters, the answer is-
The building is 40 meters.

the denominator of a fraction is 3 less than the numerator. If 5 is added to the numerator and denominator, the result is 5/6. F
Vitek1552 [10]
X=numerator
y=denominator
the sum of numerator and denominator=x+y
we suggest this system of equations:

y=x-3
(x+5) / (y+5)=5/6

we solve this system of equation by substitution method.
(x+5) / (x-3+5)=5/6
(x+5) / (x+2)=5/6
6(x+5)=5(x+2)
6x+30=5x+10
6x-5x=10-30
x=-20

y=x-3=-20-3=-23

Teh sum of the numerator an denominator=-20+(-23)=-43

Answer:    -43

5 3/12 - 1 4/9 what is the answer
Vlad1618 [11]

The answer is 3 29/36

5 3/12 = 5 9/36

1  4/9 = 1 16/36

So the answer equation is 5 9/36 - 1 16/36

                                      down: 4 45/36 - 1 16/36 = 3 29/36
