One computer processes a company's payroll in 20 minutes. while another computer takes 32 minutes. how long would it take in minutes to process payroll if both computers were used?

Time taken would be = 12 minutes to print the payroll if both computers are used

Step-by-step explanation:

Computer A Takes = 20 minutes

Computer B Takes = 30 minutes

To Find:

Time to print if both were used = ?

Solution :

Now We will first calculate How much work is done by each computer in one minute

Computer A will do = 1/20 Work one minute

Computer B will do  = 1/30 work in one minute

Now if both computers are used then

work done by both of them in one minute would be sum of both the computers f the work together

So

it would be

Work done =

Taking LCM and solving

Work done =

                   =

                   =

Now to do the whole task Time taken would be reciprocal of Work done in one minute

So

Time taken would be = 12 minutes

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
