Question

What is the value of x?

Enter your answer in the box.

__mm

Answer 1

You can set up a ratio as follows:

`(x-22)/(87.5)= (22)/(77)`

Solve for x by cross-multiplying:

`(x-22)(77) = (87.5)(22)`

`x = ((87.5)(22))/(77) + 22= 47.01`

Since we need the answer in mm and right now we have it in feet, we need a conversion ratio. After googling it, the conversion ratio is: 1ft = 304.8mm

`47.01(304.8) = 14326.64`

So, the answer is 14326.64 mm.
