The average of two numbers is 20. if one of the numbers is doubled and the other is trebled the average increase to 52

Let x and y be the two numbers. Their average is

If we multiply x and y be 2 and 3, respectively, the average becomes

We can use the two equations to make a linear system:

From the first equation we can derive

Plug this value in the second equation and we have

Now recall the relation between x and y to conclude

So, the two numbers are 16 and 24

d (5 x (-20)) * (100 x (0.7))

step-by-step explanation:

5÷1/100 * -.7 *-20

copy dot flip

5*100 * -.7 *-20

rearrange

5*-20   * 100 *-.7

-100   *-70

7000
