Answer:
x - 3
Step-by-step explanation:
(8x + 6) - (7x + 9)
8x - 7x = 1x = x
6 - 9 = -3
x - 3
In scientific notation, you need a number from 1 to less than 10 multiplied by a power of 10.
To turn 384,400 into a number from 1 to under 10, place a decimal point after the 3.
Now you have a number from 1 to less than 10.
3.844
Now count the number of places the decimal point moved left from its original position.
The decimal point was here: 384,400. after the last zero.
The decimal point moved 5 places to the left to be placed after the 3.
Since the decimal point moved 5 places left, the exponent of the 0 is 5.
384,400 = 3.844 * 10^5
