Why are the solutions to the proportions 40/8=x/10 and x/40=10/8 the same?
A because both result in the equation 8 x = 400, which simplifies to x = 5
B because both result in the equation 8 x = 400, which simplifies to x = 50
C because both result in the equation 40 x = 80, which simplifies to x = 2
D because both result in the equation 40 x = 80, which simplifies to x = 20

B

Step-by-step explanation:

B) because both result in the equation 8 x = 400, which simplifies to x = 50

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
