Two laboratory technicians are running product quality tests . One technician takes 6 minutes less than the other . What equation would give the amount of time , t , it would take to run the tests if the technicians work together to split the work on the different tests ? 1/(6t) = 1/x - 1/(x - 6) B 1/t = 1/x + 1/(x - 6) Oct t = x + x - 6 1/t = 1/x - 1/(x - 6)

Step-by-step explanation:

Let the time use by other one technician be x

if the other technician takes 6 minutes less than the first technician, then the time taken by the other technician will (x - 6)

The total amount of time t it would take to run the tests if the technicians work together will be expressed by taking the sum of the time taken by the two technician as shown.

First technician = x

Second technician = x-6

Sum of the time taken

t = x+ (x-6)

Hence option C is correct

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.
