Answer:
n = 6.4
Step-by-step explanation:
1. undo the positive 8.7 and subtract from 15.1
2. n = 6.4
The answer is: [B]: " 3.99 * 10⁻⁶ " .

Note:
______________________________________________
We are given the following answer choices, and we are asked which one is the "smallest number" :
_______________________________________________
[A]: 4.4 * 10⁻⁵
_________________________________________
[B]: 3.99 ⋅ 10⁻⁶
______________________
[C]: 2.6 ⋅ 10²
______________________
[D]: 1.85 ⋅ 10³
_______________________
We can rule out answer choices: [C] and [D]; since these values, essentially "direct us" to move the decimal point FORWARD "2 places" and "3 places", respectively; whereas choices [A] and [B] essentially "direct us" to move the decimal point BACKWARD "5 places" and "6 places" respectively. Note that all values given in the answer choices are written in proper "scientific notation" —that is, beginning with a "single integer followed by (a) decimal point(s) and then additional digits (when needed). So, the answer choice that essentially "directs us" to move the decimal point BACKWARD "6 places" —

→ Answer choice: [B]: " 3.99 * 10⁻⁶ " ;

is the smallest value ; and as such, the correct answer.

Answer:
x=3
Step-by-step explanation:
for 17.
we have that x=8 as one solution
then we have
x-8=0
so we know that
so we divide and get that
and we can factor it as
so the other solutions are
x-3 =0
x = 3
this is a normal division
24.69 x 12 = 296.28
296.28 x 1.06 = 314.06
With tax and everything, the total bill rounds up to $314.06. Hope this helped!
