Answer:
36
Step-by-step explanation:
(2x - 27) + (3x + 27)= 180 (supplementary)
2x - 27 + 3x + 27 = 180
2x + 3x + 27 - 27 = 180
5x + 0 = 180
180 ÷ 5 = x
36 = x
The value of x in given angles is 36°
What are supplementary angles?When the sum of two angles is 180°, then they are said to be supplements of each other.
Given are two angles which are supplements of each other,
Then according to definition of supplementary angles,
m∠A+m∠B = 180°
(2x − 27)°+(3x + 27)° = 180°
2x+3x = 180°
5x = 180°
x = 180°/5
x = 36°
Hence, The value of x in given angles is 36°

The length of a rectangle is four more than twice its width. If the perimeter of the rectangle is 56 cm, what is the width of the rectangle?
The width has a value of 8 meters
How to determine the value of the width?The mathematical statement from the question is given as
Length of a rectangle is four more than twice its width.
Mathematically, this can be represented as
Length = 2Width + 4
The perimeter is given as
Perimeter = 56 meters
The perimeter is calculated as
Perimeter = 2 x (Length + Width)
So, we have
2 x (2Width + 4 + Width) = 56
Divide by 2
2Width + 4 + Width = 28
This gives
3Width= 24
Divide by 3
Width = 8
Hence, the width is 8 meters

a. 12,456
If you rounded to the nearest ten thousands place. The 1 in the ten thousands place rounds down to 1, or stays the same, because the digit to the right in the thousands place is 2.
If the digit to the right is less than 5 we round toward 0.
Therefore, 12,456 was rounded down toward zero to 10,000
b. 60,792
If you rounded to the nearest ten thousands place. The 6 in the ten thousands place rounds down to 6, or stays the same, because the digit to the right in the thousands place is 0.
So, if the digit to the right is less than 5 we round toward 0.
Then 60,792 was rounded down toward zero to 60,000
c. 93, 245
Similar to the previous one, if rounded to the nearest ten thousands place. The 9 in the ten thousands place rounds down to 9, or stays the same, because the digit to the right in the thousands place is 3.
When the digit to the right is less than 5 we round toward 0.

The equation of line passes through the point (-4, -2) will be;
⇒ 3x - 4y = - 4
What is Equation of line?The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
The point on the line are (-4, -2).
And, The parallel line is,
⇒ 3x - 4y = 7
⇒ y = 3/4x - 7/4
Now,
Since, The equation of line passes through the point (- 4, -2).
So, We need to find the slope of the line.
Since, The slope of the parallel line is same.
Hence, Slope of the line is,
⇒ y = 3/4x - 7/4
m = dy/dx = 3/4
m = 3/4
Thus, The equation of line with slope 3/4 is,
⇒ y - (-2) = 3/4 (x - (-4))
⇒ y + 2 = 3/4 (x + 4)
⇒ y + 2 = 3/4x + 3
⇒ y = 3/4x + 3 - 2
⇒ y = 3/4x + 1
⇒ 4y = 3x + 4
⇒ 3x - 4y = - 4
Therefore, The equation of line passes through the point (-4, -2) will be;
⇒ 3x - 4y = - 4

Keaton knows that the slope of a certain line is m = -8/5. Does he have enough information to write the equation of the line? Explain. A. Yes the y intercept of this equation must be (0,0) so you can write the equation with only the slope value B. yes if you know the value of the slope, then you can guess the location of the y intercept and write the equation C. No, to write the equation of a line do you need to know both the Slope and one ordered pair that lies on the line D. No you don’t need to know the slope of a line to write its equation 
Answer:
C
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
the equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b ) a point on the line
To obtain either equation we require to know both the slope and one ordered pair that lies on the line.
On a coordinate plane, the y-axis is labeled imaginary and the x-axis is labeled real. Point Z 1 is (3, 1), Z 2 is (negative 2, negative 5). Point A is at (1, negative 4), B is (5, 5), C is (negative 3, 1), and D is (4, negative 2). A dotted line goes from z 1 to (0, 0), and then down to point z 2. Which point represents z1 + z2?
The sum z1 + z2 gives the point with coordinates (1, - 4), so option A is the correct one.
Which point represents z1 + z2?We know that these two points have the coordinates:
z1 = (3, 1)
z2 = (-2, - 5)
And we want to find the addition of the two points.
To add them, we just need to add the correspondent coordinates:
(3, 1) + (-2, -5) = (3 - 2, 1 - 5) = (1, - 4)
That point is the sum of z1 and z2, and we know that it is the point A, so point A is the correct option.

1. 4 = 6/a*x + 5 → x = -a/6
2. 7 + 2ax = 13 → x = 3/a
3. -ax - 20 = -14 → x = -6/a
How to Solve an Equation?To solve an equation, apply the properties of equality in order to isolate the variable solved for to one side of the equation, which gives us the solution to the problem.
1. 4 = 6/a*x + 5
4 = 6x/a + 5
Combine like terms
-6x/a = -4 + 5
-6x/a = 1
-6x/a(a) = 1(a) [multiplication property of equality]
-6x = a
-6x/-6 = a/-6 [division property of equality]
x = -a/6
2. 7 + 2ax = 13
2ax = 13 - 7
2ax = 6
Divide both sides of the equation by 2a
x = 6/2a
x = 3/a
3. -ax - 20 = -14
-ax = -14 + 20
-ax = 6
x = 6/-a
x = -6/a

Amplitude:?
Period:?
Midline: y=?
The amplitude, midline and period of the function are 3 units, 4units and 5 units respectively
How to determine the amplitude, midline, and period of the function based on the graph?
The amplitude is half the full height of the periodic function. That is:
Amplitude = (maximum - minimum)/2
Check the image attached, the maximum and minimum are labeled max and min respectively
Amplitude = (-1 - (-7))/2 = 6/2 = 3 units
The midline is the middle of the periodic graph or halfway between the minimum and maximum of the graph
Midline = (maximum + minimum)/2
Midline = (-1 + (-7))/2 = -8/2 = -4 units

What is a graph of a trigonometric function?
In these trigonometry graphs, the x-axis values of the angles are in radians, and the y-axis value of the function at each given angle is taken as f(x).
The given graph is of a negative angle of a negative cosine.
So if we draw the graph of the negative angle of a negative cosine, the graph will pass through the origin, but
If we multiply 2 from the graph of the negative angle of a negative cosine then we will get the same graph as shown in the given figure.
So the equation would be f(x) = -2cos(-x).

One plane can travel 10 miles per hour faster than another. One of them goes 135 miles in the same time it takes the other to go 130 miles. What are their speeds?
The speed of the slower plane is 260 mph and the speed of the faster plane is 270 mph.
What is the distance?Distance is defined as the product of speed and time.
Let the speed of the slower plane would be s
then (s+10) = speed of the faster
So time equation; time = dist/speed
130 / s = 135 / (s+10)
130(s+10) = 135s
130s + 1300 = 135s
135s - 130s = 1300
5s = 1300
s = 1300 / 5
s = 260
Since s = 260 mph is the speed of the slower plane
So, 270 mph is the speed of the faster.
Thus, the speed of the slower plane is 260 mph and the speed of the faster plane is 270 mph.

=================================================
Explanation:
The angles shown are known as "same-side interior" or "consecutive interior". They are interior because they are inside the parallel train tracks. They are considered "same-side" because both are below the transversal line.
If the train tracks are parallel, then those same-side interior angles are supplementary. This means they add to 180 degrees.

b) How many liters of the mixture were left
2.Mr. Alai bought a digital music player at $76.55 and a
memory card at $10.95 before sales tax. If the sales tax
was 10%, find the total amount he had to pay.
The number of bottles that could be completely filled is: 30 bottles. Additionally, he has 0.72 liters of drink left. On the other hand, the total price of the music player and memory card is $96.25 (with tax).
How to solve problem 1?To solve problem 1 we need to consider how much drink John got after mixing the honey water with the lemon juice.
10.84 + 12.2 = 23.04Subsequently, we divide the total juice in quantities of 0.75 to obtain the number of bottles that we can fill, as shown below:
32.04 / 0.75 = 30.72According to the above, 30 bottles of 0.75 liters can be filled and there would be a remaining 0.72 liters.
How to solve problem 2?To solve problem 2 we must add the value with tax of the two products
$76.55 + $10.95 = $87.5Later, to find 10% of this value we must divide it by 100 and multiply the result by 10 as shown below:
$87.5 / 100 = 0.8750.875 * 10 = $8.75Finally, we must add this value to the total value without tax ($87.5) to obtain the total value with taxes
$87.5 + $8.75 = $96.25
