Answer:
x×2+13=5
Step-by-step explanation:
We use x as the unknown number, and we just put what's in the word problem! The answer is in the question.
Equation Set-Up
x×2+13=5
Remember order of operations! (PEMDAS)
Then you solve the equation.
Because of PEMDAS, we know that multiplication is the first thing we have to do.
x×2=2x
So now, our equation looks like this.
2x+13=5
We subtract 13 from the +13 to cancel it out, but that means that we also have to subtract 13 from the 5 on the other side. We are now left with this.
2x=-8
Then, we divide -8 by 2, which gives us...
x=-4
Pablo's number is -4.
I hope I helped! Have a great day.

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

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.

In the diagram, line l is parallel to line m and is cut by transversal n. The measure of angle one is equal to 3x+6 and angle two measures 6(x−2).
What is the measure of angle one?
Answer:
24
Step-by-step explanation:
Since the lines L and M are parallel:
Angle 1 and and 2 are alternate and their measurement is equal.
3x + 6 = 6x - 12 (we multiplied 6 with inside the parenthesis)
6 + 12 = 6x - 3x
18 = 3x divide both sides by 3
6 = x to find the angle measure replace x with 6
3x + 6 is 3*6 + 6 = 24

Answer:
Question 1 : B) (8 x 20) - (8 x 1)
Question 2 : D) (2 x 9) + (2 x 3)
Step-by-step explanation:
Distributive Property is used in algebraic expressions, to divide the equation, to make it easier to solve. For question 1, since it was 20, you must subtract 8 from that answer, because 20 is 1 more than 19. For question 2, (2 x 9) + (2 x 3) would be the same thing as 2(9+3).
-kiniwih426
Answer:
B) (8 x 20) - (8 x 1)
D) (2 x 9) + (2 x 3)
Step-by-step explanation:
Distributive Property: "The distributive property tells us how to solve expressions in the form of a(b + c)."
___________________
Step 1: 8 x 19 = 152
Using PEMDAS, you can see which order to solve the equations in.
PEMDAS tells us to solve whatever is within the parenthesis first but there are 2 parenthesis and both have multiplication so just solve the first parenthesis first;
8 x 20 = 160
Step 2: We now have to solve the second parenthesis;
8 x 1 = 8
Step 3: Using PEMDAS, we see that after we solve the parenthesis, we do subtraction. So subtract 8 from 160.
160 - 8 = 152
So your answer is B) (8 x 20) - (8 x 1).
___________________
Step 1: 2(9 + 3)
Using the Distributive property, we multiply 2 by 9 and 3;
2 x 9 = 18
2 x 3 = 6
Now you are left with 18 + 6.
18 + 6 = 24
So your answer is D) (2 x 9) + (2 x 3).

Triangle N P O is shown. Line O N extends through point M to form exterior angle P N M. Angle N P O is 38 degrees. Angle P O N is 39 degrees. Exterior angle P N M is x degrees.
Which statement about the value of x is true?
x > 38
x < 39
x < 77
x > 103
Answer:
77 degrees
Step-by-step explanation:
<P + <O = 38 + 39 = 77 degrees
180 - 77 = <N = 103 degrees
180 - 103 = 77 degrees (<PNM)
