Answer:
X = 3
Step-by-step explanation:
first you would do 2 * 5x - 2 * 7 = 2x+10
second you'll get 10x- 14 = 2x + 10
third subtract the 2x by the 10x
fourth you'll get 8x
fifth then add the 14 to the 10
sixth 8x = 24
divide that by 8x to both sides
so then you get x=3

Answer:
20 m
Step-by-step explanation:
Given that :
Scale of 1 : 50 is used to make a model
If the model has a height of 40 cm ; the height of the house is:
Then, the actual height of the house is (40 * 50) = 2000 cm
Thus the height of the house in metre is :
100cm = 1 meter
2000 cm = 2000 / 100
2000 cm = 20 meter
Height of house in meter = 20 meter
