A scale measures weight to the nearest 0.1 pounds. Which is the most appropriate way to report weight using this scale?
Pani-rosa [81]
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

What is the value of X
Sindrei [870]
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 .
_________________________________
The answer is:  [C]:  " 3 " .
