What is the constant of 5 =105 then use 9 to find constant

the answer is 175.4379

step-by-step explanation:

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9
