Answer:
2,250,000 km
Step-by-step explanation:
From the above question our scale is given as:
1 m : 250000km
We are trying to find the distance between two villages which is 9m apart in kilometers
Hence
1 m : 250000km
= 1 m = 250000km
9m = x km
Cross Multiply
x km = 9 × 250,000km
x km = 2,250,000 km
4 ⁽ˣ⁺⁵⁾ = 16 (x-3)
Simplify.
4x + 20 = 16x - 48
Subtract 16x from both sides, as well as subtracting 20 from both sides.
4x - 16x = -48 - 20
Add like terms.
-12x = -68
Divide both sides by -12
x = 5 2/3
