(13) The temperature on a cold winter day is 2 degrees below zero. In the night, the temperature drops an additional 14 degrees.
EastWind [94]
Well, in the first one, 2 degrees below zero is -2 degrees, and then it says that it dropped 14 degrees, which means it dropped -14 degrees, so to know the total amount it dropped you would just have to add -2 plus -14 which is -16 degrees, so your answer for the first question would be the last answer, -16 degrees.

For the second question, just know that whenever a negative number is BY ITSELF in parentheses, that means it is used like a positive number in the equation. So (-12) automatically becomes 12. Now, since the problem is asking for a SUM, (the answer to an ADDITION problem; when you add instead of subtract), you would turn that minus symbol to a plus symbol, and add normally to get your final answer; 30 + 12 = 42. To check if this is correct, just type in <span>30 – (–12) to a calculator and you'll get the same answer! :D
Hope this helps! :3</span>

What is the sum of 3 consecutive odd integers is -39
trapecia [35]
Answer: The three consecutive odd integers are:  -15, -13, and -11 .
_______________________________________________________
Explanation:
_____________________________________________
  x + (x + 2) + (x + 4) = -39 ;
_____________________________________________
 in which "x" is one of the integers, 
           "(x + 2)" is the next consecutive odd integer;
           "(x + 4)"  is the third consecutive odd integer.
__________________________________________
By solving for "x", we can solve for each of three (3) consecutive odd integers.
________________________________________________________
     x + (x + 2) + (x + 4) = -39  ;
_________________________________________________________
          1x + 1x + 2 + 1x+ 4 = -39 ;
_____________________________________________________  
                   3x + 6 = -39 ;
______________________________________________
               Subtract  "6" from EACH side of the equation:
______________________________________________
                    3x + 6 − 6  =  -39 <span>− 6 ;
____________________________________________________
        to get:   3x = -45 ;
____________________________________________________
           Divide EACH side of the equation by "3" ;
____________________________________________________
                 3x / 3 = -45 / 3 ;
_____________________________________________________
        to get:   x = -15 ;
______________________________________________________
     x + 2 =  -15 + 2 = -13 ;
_______________________________________________________
     x + 4 =  -15 + 4 =  -11 .
___________________________________________________
Are: -15, -13, and -11 ;  Consecutive odd integers?  YES!
___________________________________________________
Does:  -15 + (-13) + (-11)  =? = -39 ??
_____________________________________________________
           -15 </span>− 13 <span>− 11 = ? 39 ??  YES!
____________________________________________________
Answer: The three consecutive odd integers are:  -15, -13, and -11.
