9514 1404 393

Answer:

  6, 9

Step-by-step explanation:

Let x represent one of the numbers. Then the other number is 15-x (because their sum is 15). The relation between the numbers is ...

  2x -3 = 15 -x . . . . . three less than twice one number is the other number

  3x = 18 . . . . . . add 3+x

  x = 6 . . . . . . divide by 3

  15-x = 9 . . . . find the other number

The two numbers are 6 and 9.

What is 1500000000000 in scientific notation
omeli [17]
1500000000000 in scientific notation is 
1.5 * 10^12
That is because you move the decimal point 12 places to the left for it to become 1.5.
1.5 * 10^12
move the decimal point 12 places to the right and you got the original number, 1500000000000.

Hope this helps!
