What THREE integers have a sum of 300?
quester [9]

Answer:

Here we will use algebra to find three consecutive integers whose sum is 300. We start by assigning X to the first integer. Since they are consecutive, it means that the 2nd number will be X + 1 and the 3rd number will be X + 2 and they should all add up to 300. Therefore, you can write the equation as follows:

(X) + (X + 1) + (X + 2) = 300

To solve for X, you first add the integers together and the X variables together. Then you subtract three from each side, followed by dividing by 3 on each side. Here is the work to show our math:

X + X + 1 + X + 2 = 300

3X + 3 = 300

3X + 3 - 3 = 300 - 3

3X = 297

3X/3 = 297/3

X = 99

Which means that the first number is 99, the second number is 99 + 1 and the third number is 99 + 2. Therefore, three consecutive integers that add up to 300 are 99, 100, and 101.

99 + 100 + 101 = 300

We know our answer is correct because 99 + 100 + 101 equals 300 as displayed above.

Add or Subtract to simplify
Drupady [299]

Answer:

3. - 8n² -8n + 3

Step-by-step explanation:

(4n^4 - 8n +4) - (8n² + 4n^4 +1)

Firstly, open the brackets.

= 4n^4 - 8n +4 - 8n² -  4n^4 - 1

Now, group like terms.

= 4n^4 - 4n^4 - 8n² -8n - 1 + 4

4n^4 - 4n^4 cancel out with each other since one is negative and the other is positive. So we're left with - 8n² -8n - 1 + 4

= - 8n² -8n - 1 + 4

= - 8n² -8n + 3

What is the equation
katovenus [111]
The correct answer is:    [A]:  " x + 2y = -11 " .
________________________________________________
Explanation:
_________________________________________________
First, we narrow down to choices:

         [A]:  "x + 2y = -11  ;  and:  [D]:  "2x + y = -10 " ;

since these are the only answer choices that the point "(-3, -4) pass through.

Now, write these in "slope-intercept form" (a.k.a. "point-slope form"); that is:

  y = mx + b ;

and see which one has the slope of "(-1/2)"  (i.e. "m = -1/2") ;
_____________________________________________________
Start with Answer choice  [A]:  "x + 2y = -11 " ;

                                               ↔ 2y + x = -11 ;
                                                 
                                            Subtract "x" from each side:
                                                    2y + x − x = -11 − x ;

                                            to get:  2y = -11 − x ; 
                                
                                               ↔   2y = -11 + (-x) ;
  
                                               ↔   2y = -x + (-11) ;

                                               ↔   2y = -1x − 11 ;
______________________________________________
Divide EACH SIDE of the equation by "2" ;
______________________________________________
                                            2y / 2  = (-1x − 11) / 2  ;
         
                                           to get:   y = (-1/2)x − (11/2).

So:  Answer choice:  [A]: should be the correct answer .
______________________________________________
Let us try Answer choice: [D] ;  just to rule out this possible answer:

                                                   " 2x + y = -10 " ;
                   
                                               ↔  y + 2x = -10 ;
                     
                                    Subtract "2x" from EACH SIDE of the equation ;

                                                    y + 2x − 2x = -10 − 2x ;
    
                                                               y = -10 − 2x ;
                 
                                                         ↔  y =  -10 + (-2x) ;

                                                         ↔  y = -2x + (-10) ;
          
                                                         ↔  y = -2x − 10 ;

                         The slope of: Answer choice [D]: is "-2" ;  NOT "(-1/2)".

So; we confirm that:  Answer choice: [D]:  is INCORRECT.
_________________________________________________________
So the correct answer is:  Answer choice:  [A]:  " x + 2y = -11 " .
