Answer:
12
Step-by-step explanation:
First figure the ratio of the real building to the model which is 21 divide 3. So the ratio is 1:7, since we're finding the height of the model, we divide 7 by 84 which is 12
Given -:
EF = 2X-7
FG = 4X-20
EG = 21
FIND OUT
EF =?
FG = ?
To proof
as given in the question
we have the value of EF = 2X-7 , FG = 4X-20 and EG = 21
Thus we have
EG = EF + FG
21 = 2X-7 + 4X- 20
21 = 6x - 27
48 = 6x
x = 8
Hence proved
Now put this value
![EF = 2\times 8 - 7\\EF = 9](https://tex.z-dn.net/?f=EF%20%3D%202%5Ctimes%208%20-%207%5C%5CEF%20%3D%209)
Now
![FG = 4\times 8 - 20\\FG = 12](https://tex.z-dn.net/?f=FG%20%3D%204%5Ctimes%208%20-%2020%5C%5CFG%20%3D%2012)
Hence proved
Answer:
C.
Step-by-step explanation:
Adding to the x value makes a point go appear more right. Subtracting some from the y value makes a point go appear down.
