Answer:
Real distance between Manchester and London = 263.2 km
Step-by-step explanation:
Given that:
A map has a scale of 1 cm = 14 km
Ratio = 1 : 14
Distance from Manchester to London = 18.8 cm
Let,
x be the real distance between Manchester and London.
Ratio = 18.8 : x
As the relationship is proportional,
1 : 14 :: 18.8 : x
Product of mean = Product of extreme
14*18.8 = x
x = 263.2 kilometers
Hence,
Real distance between Manchester and London = 263.2 km

Answer:
x=1
Step-by-step explanation:
To solve, we need to get x by itself. To do this, preform the opposite of what is being done to the equation, and everything that is done to one side, must be done to the other.
5(2x-8)+15= -15
First, subtract 15 from both sides, since 15 is being added
5(2x-8)+15-15=-15-15
5(2x-8)=-30
Next, divide both sides by 5 since 5 is being multiplied
5(2x-8)/5= -30/5
2x-8= -6
Add 8 to both sides, since 8 is being subtracted
2x-8+8= -6+8
2x= 2
Divide both sides by 2, since 2 is being multiplied
2x/2= 2/2
x=1
