8.45
Based on my understanding of standard form I believe that this would be the answer.
3.15*10 + 4.7*10 + .6*10
Actually the answer would be the equation solved 8.45 then the standard form of that would be 8.45*10 to the zero power.
The
315 million written in standard form is 315,000,000.
315,000,000
315 = three hundred fifteen.
3.15 × 102
15x+25y = 315 25y = -15x+315 y = -0.6x+12.6 which is now in slope-intercept form
315 million written in standard form is 315,000,000.

315 = three hundred fifteen.

3.15 × 102
15x+25y = 315 25y = -15x+315 y = -0.6x+12.6 which is now in slope-intercept form
1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
315 + 68 = 383
It is: 315 = CCCXV
0.2984
Well, it's easier to read, write, and say. For example: if you had the number 315, you know what it is right away. But, if standard form wasn't used, then you would have to say: 300+10+5 which is harder to read, write, say, and understand. Also, it would be harder for people to solve equations because they're so focused on how to write it that they lose thought to what could be a big find! Who would want to solve: fifty-two+ninety+one hundred sixty-five million, four hundred seventy-nine+x= two hundred? :)
