Employee 2 can finish washing a car in 20 minutes.
.
How long will it take the tiro employees to wash a car together?

60 minutes

Step-by-step explanation:

Given that Employee I can finish washing a car in 30 minutes. and

employee 2 can finish washing a car in 20 minutes.

Assuming that both will wath the car together after n minutes.

So, n must be the integral multiple of 30 as well as 20.

For niminum value of n,  n must be the lowest common factor of 30 and 20.

Hence, after 60 minutes, they will wash a care togethre.

the difference between a number and 5 is -2.

step-by-step explanation:

notice that the equation you are given has -2 (negative 2) on the right side, not 2. when you subtract 5 from a number n, you are finding the difference between the number and 5.

the difference between a number and 5 is -2.

21/58.
