Answer:

43 & 96

Step-by-step explanation:

x=one number

y=other number

x+y=139

x-y=53 x=y+53

substitute for x

y+53+y=139

reduce

2y+53-53=139-53

2y=86

2y/2=86/2

y=43

x=96

Answer:

Step-by-step explanation:

The average of paid time off is the sum of the paid time off (T) of each employee divided by the number of employees(n):

av = (∑T)/n

Thus, av is directly proportional to the sum of T and indirectly proportional to n. It means that if T raises, the average raises too. So, the manager must fire the employees who have the least number of days off, so T will increase.

To solve this you can make a proportion where the matching sides will correspond to each other. It should look something like this:

$\frac{AC}{PD} =\frac{CR}{DR}$

$\frac{10}{15} =\frac{x}{42}$

Now you must cross multiply

10*42 = 15*x

420= 15x

To isolate x divide 15 to both sides

420/15 = 15x/15

28 = x
