The numbers are:
3.9 × 105 = 409.5
6.1 ×103 = 628.3
9.3 × 105 = 976.5
1.6 × 103 = 164.8
Arranging from greatest to least and in scientific notation form gives:
9.3 × 105 , 6.1 × 103 , 3.9 × 105 , 1.6 × 103

Answer:
7 & 13
Step-by-step explanation:
Let the first number be x
2nd number = 8 less than 3 times the other
2nd number = 3x - 8
Their sum = 20
X + 3x - 8 = 20
4x -8 = 20
Collect like terms
4x = 20+8
4x = 28
Divide both sides by 4
4x/4 = 28/4
X = 7
First number = 7
2nd number = 3x - 8
= 3(7) - 8
= 21 -8
= 13.
Therefore the numbers are 7 and 13
