The midpoint of the line segment CD whose coordinates (-2,-4) and D (6,2) will be (2, -1).
What is the mid-point of the line segment?Let AB be the line segment and C be the mid-point of line segment AB. Let the coordinate of point A (x₁, y₁), the coordinate of point B (x₂, y₂), and the coordinate of the mid-point (x, y).
Then the coordinate of the mid-point of the line segment is given as,
(x, y) = [(x₁ + x₂) / 2, (y₁ + y₂) / 2]
The endpoint of the segment CD is given as C(-2, -4) and D(6, 2). Then the mid-point of the line segment CD will be
(x, y) = [(-2 + 6) / 2, (-4 + 2) / 2]
(x, y) = (4/2, -2/2)
(x, y) = (2, -1)
The midpoint of the line segment CD whose coordinates (-2,-4) and D (6,2) will be (2, -1).

if there are 200 questions and 4 marks for correct answers and -1 for incorrect answer and total marks is 250then what is the number of correct answers
The number of questions answered correctly = 90.
What is a system of linear equations?A system of linear equations is a set of two or more linear equations. Linear equations refer to the equations that involve two or more variables in the form of "ax + b".Now,
Given:
Total number of questions = 200Marks for correct answer = 4Marks for incorrect answer = -1Total marks = 250To find : Number of correct answers = ?
Finding:
Now, assuming that the student attempted and answered all the questions,
Let the number of questions correctly answered be x and incorrectly answered be y.Then,
x + y = 200 (For number of questions) (eqn 1)and 4x - y = 250 (For the marks scored) (eqn 2)Solving the system of linear equations:
For eqn 2, we get that y = 4x - 250
Substituting in eqn 1, we get:
=> x + 4x - 250 = 200
=> 5x = 250 + 200 = 450
=> x = 90
That is, the number of questions answered correctly = 90, the incorrect answers = 200 - 90 = 110.

#3: The Hansen family bought 2 child and 2 adult movie tickets and paid $36.50. The Owens family bought 5 child and 2 adult tickets and paid $60.50. How much does a child movie ticket cost? *
Answer:
Cost of child movie = x = $8
Cost of adult movie = y = $10.25
Step-by-step explanation:
Let cost of child movie = x
Cost of adult movie = y
Now converting statements into mathematical expressions:
Hansen family bought 2 child and 2 adult movie tickets and paid $36.50.
[tex]2x+2y=36.50[/tex]
Owens family bought 5 child and 2 adult tickets and paid $60.50. [tex]5x+2y=60.50[/tex]
Let:
[tex]2x+2y=36.50--eq(1)\\5x+2y=60.50--eq(2)[/tex]
Subtract both equations:
[tex]2x+2y=36.50\\5x+2y=60.50\\- \:\:\: - \:\:\:\:\:\:\:\: -\\--------\\-3x=-24\\x=\frac{-24}{-3}\\x=8[/tex]
So, we get Value of x =8
Now, putting value of x in eq(1) to find value of y
[tex]2x+2y=36.50\\Put \: x=8\\2(8)+2y=36.50\\2y=36.50-16\\2y=20.5\\y=\frac{20.5}{2}\\y=10.25[/tex]
So, we get Value of y = 10.25
So,
Cost of child movie = x = $8
Cost of adult movie = y = $10.25

the sum of three numbers is 87. the second number is 2 times the third. the first number is 5 less than the third. what are the numbers?
The required numbers are 18,46 and 23.
This problem requires the idea of linear equation of 1 variable.
To clear up the linear equation we also need to recognize the BODMAS policies and the way to solve algebraic equations.
in this query the sum of the 3 numbers is 87.
let us count on that the third variable be x.
the second one variable is 2x.
The first variable is (x-5).
Now according to the question,
[tex](x-5)+2x+x=87[/tex]
⇒ [tex]4x-5=87[/tex]
⇒ [tex]4x=87+5[/tex]
⇒[tex]4x=92[/tex]
⇒ [tex]x=\frac{92}{4}[/tex]
∴ x=23
So, the third number is 23.
The second number is 2x i.e., 46.
The first number is (x-5) i.e., 18.

Find the measure of each missing angle.
Answer:
Angles 1 and the angle provided (88°) are supplementary meaning their angles with total 180°. Therefore m<1 +88=180
m<1=92
We can see that by the arrow on the 2 lines that they are parralel and paralel lines form congruent angles. Therefore, the m<64 will equal that of 3
m<3=64
Now, that we have the m<1 and the m<3 we know that the m<2 is 24
This is because the measure of the interior angles of any triangle add up to 180.
92+64+m<2=180
156+m<2=180
m<2=24
Now, we see that the m<3+m<4+81 will total 180°. the m<3 is 64 so:
64+81+m<4=180
145+m<4=180
m<4=35
Now, by using the rule that the measure of the interior angles of any triangle add up to 180 we see that the m<4+m<5+64=180
m<4=35
35+64+m<5=180
99+m<5=180
m<5=81

You need a 40% alcohol solution. On hand, you have a 520 mL of a 70% alcohol mixture. How much pure water will you need to add to obtain the desired solution?
The 390 ml of pure water will you need to add to obtain the desired solution.
It is required to find how much pure water will you need to add to obtain the desired solution.
What is percentage?A part of a whole expressed in hundredths a high percentage of students attended. Also the result obtained by multiplying a number by a percent the percentage equals the rate times the base.
Given:
You know that the current solution is 70% alcohol, so the amount of alcohol present is 70% of 520 = 364
Let x be the amount of water to add. Then the new total amount would be 520 + x. To arrive at a solution that is 40% alcohol, you would want the amount of alcohol to be 40% of the new total.
So...
364 = .40 * (520 + x)
By simplify we get,
364=208+0.40x
364-208=0.40x
156=0.40x
x=390 ml
we must add 390 ml of water to get the 40% solution.
Therefore, the 390 ml of pure water will you need to add to obtain the desired solution.

Solve: |11x + 10| = 22
To solve the equation |11x + 10| = 22, we need to consider two cases: one where the expression inside the absolute value is positive and one where it is negative.
Case 1: (11x + 10) is positive:
In this case, the equation becomes 11x + 10 = 22. Solving for x, we subtract 10 from both sides, resulting in 11x = 12. Dividing by 11 gives x = 12/11.
Case 2: (11x + 10) is negative:
Here, the equation becomes -(11x + 10) = 22. Simplifying, we have -11x - 10 = 22. Adding 10 to both sides gives -11x = 32. Dividing by -11 yields x = -32/11.
Thus, the solution set for the given equation is x = 12/11 and x = -32/11, representing the two possible values of x that satisfy the equation |11x + 10| = 22.
