Is will like to make this as simple as i can. -1 x 372 - -31= what

  The correct answer is:  " - 341 " .

Step-by-step explanation:

  -1 × 372 − -31 =  

 (-1 *372) −(-31) =

 (-1*372)  + 31 ;   {since "subtracting a negative value" is the same value as "adding that value's positive value"} ;

           = - 372 + 31

          =  - 341  

The answer is:  " - 341 " .

Note:  Using the "Order of Operation rules":

 PE MD AS ;

 "Please Excuse My Dear Aunt Sally" ; →  "mnemonic device" ;

In which "Parentheses" (if they occur) are considered first;

              then:  "Exponents" (if they occur):

              then:  "Multiplication and Division" (if any of these occur; from the left of the equation—and continuing to the right of the equation—in the order in which they occur; neither the multiplication nor the division take priority over each other);

              then:  "Addition and Subtraction: (if any of these occur; from the left of the equation—and continuing to the right of the equation—in the order in which they occur; neither the addition nor the subtraction take priority over each other).

We are given the expression:

   →  " -1 × 372  −  -31 " ;

Note, there are no "parentheses" or "exponents";

There is "one" multiplication but no "division".

There is "no" addition; but there is "one" subtraction.

so, the multiplication comes first:

 →  " -1 *372  =  -372 ;

Now, let us continue with the "one" subtraction that remains:

"  -372  −  -31 " ;

→  {Note that "subtracting a negative value" is the same value as                            

                          "adding that value's positive value"} ;

So, " - 372 −  -31  =  -372 + 31  =  - 341 . "

The correct answer is: " - 341 " .

Hope this helps!

Wishing you the best!

step-by-step explanation:

32.50-7.50=25

225/25=11

starting with:    

5 + x - 12 = 2x - 7   

5 + x - 12 - x = 2x - 7 - x (subtract x from both sides)   

5 - 12 = x - 7 (combine and cancel x's from both sides)   

5 - 12 + 7 = x - 7 + 7 (add 7 to both sides)   

0 = x (add numbers together on both sides)       

so in order for the equation to be true, x must be 0.   

trying x = -0.5   

5 + x - 12 = 2x - 7 (original equation)   

5 + -0.5 - 12 = 2(-0.5) - 7 (plug in value of x)   

5 + -0.5 - 12 = -1 - 7 (did multiplication)   

-7.5 = -8 (did addition on both sides)       

since -7.5 is obviously not equal to -8, the value of -0.5 for x is wrong.   

trying x = 0   

5 + x - 12 = 2x - 7 (original equation)   

5 + 0 - 12 = 2(0) - 7 (plug in value of x)   

5 + 0 - 12 = 0 - 7 (did multiplication)   

-7 = -7 (did addition on both sides)       

since -7 equals -7, that demonstrates that the value of 0 for x is correct.   

trying x = 1   

5 + x - 12 = 2x - 7 (original equation)   

5 + 1 - 12 = 2(1) - 7 (plug in value of x)   

5 + 1 - 12 = 2 - 7 (did multiplication)   

-6 = -5 (did addition on both sides)       

since -6 is obviously not equal to -5, the value of 1 for x is wrong.
