To find b, start by subtracting 20 from both sides:
50 = -1/3b + 20
-20 -20
30 = -1/3b
Now isolate b by dividing both sides by -1/3:
30/(-1/3) = (-1/3b)/(-1/3)
-90 = b
b is 90!

solve this equation 8+8x=8
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 " .

The equation of the line through the point (-4, 7) and with a slope of -5/2 is y = -5/2x - 3
The equation of a line in slope intercept form is expressed as:
[tex]y-y_0 = m(x-x_0)[/tex]
m is the slope
(x0, y0) is the point on the line.
Given the following parameters:
m = -5/2 and (x0, y0) =(-4, 7)
Substitute the given coordinates into the formula above;
y - 7 = -5/2(x + 4)
2(y-7) = -5(x+4)
2y-14 = -5x - 20
2y = -5x - 20 + 14
2y = -5x - 6
y = -5/2x - 3
Hence the equation of the line through the point (-4, 7) and with a slope of -5/2 is y = -5/2x - 3

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?
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

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
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.

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