A local hamburger shop sold a combined total of 575 hamburgers and cheeseburgers on Sunday. There were 75 fewer cheeseburgers sold than hamburgers. How many hamburgers were sold on Sunday?

Answers

Answer:

250 Hamburgers

Step-by-step explanation:

575 is total

Hamburger is x

Cheesburgers is (x-75) as it is 75 less than the number of hamburgers

x + (x-75) = 575

2x -75 = 575

2x = 500

x = 250

Convert to Slope-Intercept Form to graph 3x + 2y = 8.

Answers

Answer:

y= - 3/2x+4 or y= - 1.5x+4

Step-by-step explanation:

Slope Intercept Form: y=mx+b

3x+2y=8

2y= - 3x+8

y= - 3/2x+4 or y= - 1.5x+4

Convert to Slope-Intercept Form to graph 3x + 2y = 8.The Slope : -3/2The y-intercept: y = -3x/2 + 4

What is Slope?
The ratio of how much y grows as x grows by a certain amount is known as a line's slope. The slope of a line indicates how steep it is, or how much y rises as x rises. Anywhere along the line, the slope remains constant (the same).

Solve the equation for y resulting in the y = mx + b
Where,
m = slope
b = the y intercept think b beginning.
3x + 2y = 8
Subtracting 3x both side
3x + 2y - 3x = 8 - 3x2y = 8 - 3x
Dividing both side by 22y/2 = 8/2 - 3x/2y = 4 - 3x/2y = -3x/2 + 4
So, m = -3/2and b = 4

Hence, Slope-intercept is y = -3x/2 + 4

Maria conducted an in-person pre-election survey about voter preferences in the Democratic primary. She found that nearly all respondents (98 percent) were open to supporting a woman candidate. However, in the anonymous follow-up survey that re-interviewed the respondents, only 80 percent responded that they would be open to supporting a woman candidate. What could be generating these different results

Answers

Answer:

the social desirability effect

Step-by-step explanation:

Social-desirability biases is the sort of response bias that is the tendency of the survey respondent to answer the question in a manner that is favorable to others.

As Maria found that most respondents 98% of the voters were open to support women candidates. The social desirably bias poses a serious problem during the self-reporting as the bias interferes with the interpretations of the average tendencies. As however during the anonymous survey of the voters or respondents showed only 80% of them would support the women candidate.

Hence the social desirability bias is the main culprit for such a response.

solve this equation 8+8x=8

Answers

Hello!

Answer:

x=0

Step-by-step explanation:

Hope this helps!

Answer:  The correct answer is:  " x = 0 " .

________

Step-by-step explanation:

Given:  " 8 + 8x = 8 " ;  Solve for "x" ;

________

Method 1)

________

Subtract "8" from each side of the equation:

________

  → " 8 + 8x − 8 = 8 − 8 " ;

  → On the "left-hand side" of the equation:

          Note the following "like terms" :

            " +8 − 8 = 0 " ;

  →  and we are left with "8x" on the "left-hand side" of the equation.

  → On the "right hand side" of the equation:

         The "(8 − 8)" = 0 ;

________

And we are left with:

  →  " 8x = 0 " ;

________

Now, divide each side of the equation by "8" ;

   to isolate "x" on one side of the equation;

   & to solve for "x" :

________

  →  8x / 8 =  0/8 ;

to get:

  →  " x = 0 " ;

  →  which is the correct answer.

________

Method 2)

________

Given:  " 8 + 8x = 8 " ;  Solve for "x" ;

________

Subtract "8" from each side of the equation; in the following manner:

________

   8  +  8x    =    8 ;

 - 8             =   - 8 ;

_____________

   0  +  8x    =    0 ;

→ We have:  " 0 + 8x = 0 " ;

Note: On the "left-hand side" ; we have:

                 " 0 + 8x " ;

  We can simplify this to "8x" ; since the "addition property of zero" states that when "0" is added to any value; the resulting value does not change.

Now, we can bring down the "0" from the "right-hand side" of the equation;

And we can rewrite our equation as:

________

   → " 8x = 0 " ;

Now, divide each side of the equation by "8" ;

   to isolate "x" on one side of the equation;

   & to solve for "x" :

________

  →  8x / 8 =  0/8 ;

to get:

  →  " x = 0 " ;

  →  which is the correct answer.

________

Method 3)

________

Given:  " 8 + 8x = 8 " ;  Solve for "x" ;

________

Divide each side of the equation by "8" ;

________

  → " [tex]\frac{(8 + 8x)}{8} =\frac{8}{8}[/tex] " ;

________

To solve:

________

Note: On the "right-hand side" of the equation:

________

Take note that: " [tex]\frac{8}{8} =[/tex] (8 ÷ 8) = 1 " ;

________

Rewrite the equation as:

________

 →  " [tex]\frac{(8 + 8x)}{8} =1[/tex]  "  ;

________

To solve:

________

Note:  " [tex]\frac{x}{y} = z[/tex] " ;  ↔ [tex]x = z*y[/tex] ; [tex](y\neq 0)[/tex] ;

________

 →  " [tex]\frac{(8 + 8x)}{8} =1[/tex]  "  ;  

 →  From the "left-hand side" of the equation;

      Let us simplify:

________

 →  " [tex]\frac{(8 + 8x)}{8} = \frac{8}{8} + \frac{8x}{8} = 1 + x[/tex] " ;  

Now, bring down the "1" from the "right-hand side" of the equation;

and rewrite the equation:

________

 →  " 1 + x = 1 " ;

Now, subtract "1" from each side of the equation;

   to isolate "x" on one side of the equation;

   & to solve for "x" :

________

     " 1 + x − 1 = 1 − 1 " ;

  → On the "left-hand side" of the equation:

          Note the following "like terms" :

            +1 − 1 = 0 " ;

  →  and we are left with "x" on the "left-hand side" of the equation.

  → On the "right hand side" of the equation:

         The "(1 − 1)" = 0 ;

  → And we are left with:

      →  " x = 0 " ;

      → which is the correct answer!

________

The correct answer is:  " x = 0 " .
