Determine the gear ratio for a bike with 45 front teeth and 18 rear sprocket teeth.

18/45 = 0.4

45/18 = 2.5

18(45) = 810

45 – 18 = 27

just did it, it's 45/18 = 2.5
hope this : )
have a gr8

a 10 percent increase

the answer is 489

step-by-step explanation:

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )

answer:   x*94 +688*6   = 267*100

94x+4128=26700    

94x=22572     /94

x=240.128
