Answer:
C. 14 is the answerStep-by-step explanation:
1. Write the question.
17 - 2x = -11
2. Subtract 17 from both sides
-17 -17
- 2x = -28
3. Negatives cancel
2x = 28
4. Divide both sides by 2
/2 /2
x = 14
5. Check the answer, write the equation.
17 - 2x = -11
6. Substitute x with the value
17 - 2(14) = -11
17 - 28 = -11
-11 = -11
The answer is correct!
So, 14 is the answerHope this helped,

Prince Ivan rides gray wolf and a constant speed from kings castle to the magic apple garden in five hours. on the return trip to kings castle gray wolf runs at that original constant speed for the first 36 km then runs the rest of the way 3 km/h faster. what was grey Wolf original speed if the return trip took 15 minutes less than the trip from kings castle to magic apple garden?
ahhh i rlly need help with this one haha thanks!!
Answer:
The original speed of the grey wolf can be 9 and/or 48 km/hour
Step-by-step explanation:
There are two trips. One to King Castle (KC) to Magic Apple Garden (MAG), and then back (MAG - KC).
First trip: KC - MAG
It takes the same distance as MAG - KC so distance can be D for both.
Then it is stated that it takes 5 hours or 300mins for him to go from KC - MAG, and the speed is constant.
Let x be speed.
So the equation for this is:
D=5x
Second trip: MAG - KC
Here he goes 36 mi at constant speed (x), then picks up his speed by 3 km/hour (x+3).
For Time:
He reaches to KC, 15 mins earlier than KC - MAG, so he reaches there in 4.75 hours or in 275 min.
The problem splits into two as there are two different times, for the two parts of the journey or distance for MAG - KC.
Let T#1 = a, and T#2 = b.
Let D#2 = D-36
The equation for a:
a = 36/x --> This is he is at a constant speed and went for 36mi.
Next:
The equation for b:
b = (x+3)/D#2
These two equation have to be added as (a+b) = 4.75 --> 4.75 is the total time for MAG - KC.
So the equation is:
36/x + (5x-36)/x+3 = 4.75 --> Knowing (a+b) = 4.75, just put 4.75 as the equal, and add the fractions that equal (a) and (b).
Now Solve:
36/x + (5x-36)/x+3 = 4.75
0.25s^2 + 108 + 5s^2 - 36s = 4.75s*(s+3)
0.25s^2 - 14.25s + 108 = 0
(14.25 +- Square root (203.06 - 108))/0.5
(14.25 +- Square root (95.0625))/0.5
(14.25 +- 9.75)/0.5
Answer:
s = 9, s=48.
Therefore the original speed of the grey wolf can be 9 and/or 48 km/hour.
Over a 5-year period, a company reported annual profits of $8 million, $3 million, $2 million, and $9 million. In the fifth year, it reported a loss of $7 million. What was the mean annual profit?
Given
Annual profits of four years $8 million, $3 million, $2 million, and $9 million.
In the fifth year, it reported a loss of $7 million.
To find:
The mean annual profit.
Solution:
Formula for mean is:
[tex]\text{Mean}=\dfrac{\text{Sum of observations}}{\text{Number of observations}}[/tex]
Annual profits are $8 million, $3 million, $2 million, $9 million and -$7 million. Here negative sign represent loss.
So, the mean annual profit is:
[tex]\text{Mean}=\dfrac{8+3+2+9+(-7)}{5}[/tex]
[tex]\text{Mean}=\dfrac{22-7}{5}[/tex]
[tex]\text{Mean}=\dfrac{15}{5}[/tex]
[tex]\text{Mean}=3[/tex]
Therefore, the mean annual profit is $3 million.

the scatterplot shows the number of hours that 12 people spent learning to type on a keyboard and each persons average typing speed. Based on the scatterplot, what is the best prediction of a persons average typing speed in words per min. if the person has spent 70 hours learning to type?
Answer:
85 wpm
Step-by-step explanation:
From the scatter plot, we can see the following;
At 20 hours, average typing speed = 34 wpm
At 30 hours, the average typing speed = 40 wpm
At 40 hours, the average typing speed = 51 wpm
At 50 hours, the average typing speed = 65 wpm
Average differences = ((40 - 34) + (51 - 40) + (65 - 51))/3 = 10.3
Approximating to a whole number = 10
Now, we can approximate that at 60 hours, average typing speed = 65 + 10 = 75 wpm
At 70 hours, the average typing speed = 75 + 10 = 85 wpm
Answer:
85 wpm

K divided by 5 = 12.4
Answer:
k=62
Step-by-step explanation:
K divided by 5 = 12.4
Multiply both sides by 5
5k/5=12.4×5
Simplify;
k=62
Hope this helped!!
Answer:
k = 62
Step-by-step explanation:
To solve we need to get k on one side alone.
To do this we can multiply buth sides by 5
[tex]\frac{k}{5} =12.4[/tex] ---> =12.4*5
This gives us x=62
You can check this by putting 62 in for k and solving the problem.
Max gets a weekly allowance of $17. He spends $3 each week on snacks. He splits the rest of his allowance into equal amounts for his college fund and spending money. How much money does Max keep for spending money each week? $
Answer:
$7
Step-by-step explanation:
The amount max keeps for spending = 1/2(total allowance - amount he spends on snacks)
total allowance = $17
amount he spends on snacks = $3
Amount he would have for his college fund and spending money. = $17 - $3 = $14
Since he splits the amount equally between his college fund and spending money, the amount he would have for spending can be determined by dividing 14 by 2
$14/2 = $7

Incomplete question;
I will answer this question with the attached dot plot
The horizontal axis represents the friends, the vertical represents the number of baseball trading cards and the dots represent the frequency
So, we have:
[tex]Friend\ 1 = 2[/tex]
[tex]Friend\ 2 = 3[/tex]
[tex]Friend\ 3 = 7[/tex]
[tex]Friend\ 4 = 4[/tex]
[tex]Friend\ 5 = 2[/tex]
[tex]Friend\ 6 = 6[/tex]
[tex]Friend\ 7 = 2[/tex]
[tex]Friend\ 8 = 5[/tex]
[tex]Friend\ 9 = 1[/tex]
[tex]Friend\ 0 = 0[/tex]
The friends that has more than 5 are:
[tex]Friend\ 3 = 7[/tex]
[tex]Friend\ 6 = 6[/tex]
Hence, 2 friends have more than 5 cards

Alan and Beth share $1190 in the ratio Alan : Beth = 5:2.
Work out how much Alan receives.
options:
$850
$1666
$34
$119
The share of money Alan receives is $850. Therefore, option C is correct answer.
Given that, the total amount is $1190 and the ratio Alan: Beth = 5:2.
We need to find the how much money Alan gets.
What is the ratio?The quantitative relation between two amounts shows the number of times one value contains or is contained within the other.
Now, 5+2=7
Money Alan receives=5/7×1190
=$850
The share of money Alan receives is $850. Therefore, option C is correct answer.

What is the name of the blue dot located inside the curve of the parabola
below?
O A. Focus
B. Center
O C. Directrix
D. Vertex
The blue dot located inside the curve of the parabola is Focus.
What are Parts in Parabola?
The essential feature of a parabola is that all of its points are the same distance from a point called the focus and a line called the directrix. The vertex, axis, latus rectum, and focal length are also key components of a parabola.
The latus rectum, also known as the focal diameter, is the line segment that runs through the focus and parallel to the directrix. The focal diameter's endpoints are located on the curve.
A parabola is the set of all points ( x, y ) in a plane that are the same distance from a fixed line called the directrix and a fixed point not on the directrix (the focus).
A parabola will have three key components: a focus, a directrix, and a vertex. This upward-opening parabola demonstrates that all points,, along the parabola's curve will be the same distance from the focus and the directrix.
Thus, the blue dot located inside the curve of the parabola is Focus.

Which theorem can you use to show that the quadrilateral on the tile floor is a parallelogram?
Answer:
Parallelogram Theorem #1 Converse
Step-by-step explanation: : If each of the diagonals of a quadrilateral divide the quadrilateral into two congruent triangles, then the quadrilateral is a parallelogram. Parallelogram Theorem #2 Converse: If the opposite sides of a quadrilateral are congruent, then the quadrilateral is a parallelogram.
Parallelogram opposite sides converse. Therefore, option A is the correct answer.
What is parallelogram?A parallelogram is a special kind of quadrilateral that is formed by parallel lines. The angle between the adjacent sides of a parallelogram may vary but the opposite sides need to be parallel for it to be a parallelogram. A quadrilateral will be a parallelogram if its opposite sides are parallel and congruent.
Let the diagonals AC and BC intersect at O.
Consider, triangle BOC and triangle AOD
OA=OC (Shown in the figure)
∠AOD=∠BOC (Vertically opposite angles are equal)
BO=DO (Shown in the figure)
By SAS congruence theorem
triangle BOC and triangle AOD are congruent
So, by CPCT AD=BC
Similarly,
From, triangle AOB and triangle DOC
AB=DC
Therefore, option A is the correct answer.
