The solution to the equation includes both the positive and negative portions of the solution. x = 12, -12
33.3 because 27/50=36/x and x=66.67 and thats how much as decayed after 36 hours but you want what is left so subtract from 100 and get 33.3
The question is kind of vague in my opinion.
the best measurement to report with the scale in my opinion would be tens of pounds. my reasoning is because the decimal place would still prove importance with numbers under one hundred. above one hundred pounds and the decimal place becomes kind of pointless.
I hope I answered your question. though i'm sorry if i didn't
The answer is: [C]: " 3 " .

Explanation:
__________________________________
4x - 1 = 2x + 5 ; Solve for "x" ;
__________________________________
Subtract "2x" from each side of the equation; and add "1" to each side of the equation:
___________________________________________________
4x - 1 - 2x + 1 = 2x + 5 - 2x + 1 ;
___________________________________________________
2x = 6 ;
_________________________________
Divide EACH side of the equation by "2" ; to isolate "x" on ONE side of the equation; and to solve for "x" ;
_________________________________
2x / 2 = 6 / 2 ;
_________________________________
x = 3 .

<span>x + 1/2 = 3/4
</span><span>x + 2/4 = 3/4
x = 3/4 - 2/4
x = 1/4
answer
</span><span>x = 1/4</span>
