Answer:
Step-by-step explanation:
The two inside angles will sum to 180°.
The top to angles are equal.
Think about this as what if both of the parallel lines were intersected by a perpendicuar line. Every angle would be a right triangle 90°. The inside angles will sum to 180° and the opposite angles are again equal.
(2x + 18) + (8x + 12) = 180
10x + 30 = 180
10x = 150
x = 15
-------------------------
(3y - 18) = (8x + 12) x = 15
(3y - 18) = (8(15) + 12)
(3y - 18) = (120 + 12)
(3y - 18) = 132
3y = 132 + 18
3y = 150
y = 50
Pls help and thank you guysss
Answer:
x=8
Step-by-step explanation:
These two equation should add up to equal 180.
8x+13+12x+7=180
20x+20=180
20x=160
x=8
Answer:
8x+13+12x+7 =180
20x+20 =180
x= 8

Answer: They are related by the AAS postulate and they can be proven congruent.
Step-by-step explanation: You can see that one of the lines on each of the triangle has that little tick which means those lines are congruent. You can also see that for two of the angles one of them has one arc and the other has two arcs for BOTH triangles which makes those two angles congruent. Two angles and one side congruent makes the triangles congruent by the AAS postulate.

It cost $5 to send 6 packages through a certain shipping company. Consider the number of packages per dollar. Find the constant of proportionality for this situation. ENTER ONLY A NUMERICAL ANSWER. NO WORDS, SYMBOLS, OR ADDITIONAL SPACES
Answer:
1.2 packages per dollar
Step-by-step explanation:
Number of packages = 6
Total cost in dollars = $5
Number of packages per dollars = Number of packages / Total cost in dollars
= 1.2 packages per dollar
Let
P = number of packages
d = cost in dollars
k = constant of proportionality
P = k * d
6 = k * 5
k = 6/5
k = 1.2
Constant of proportionality = 1.2

George scored 70, 92, 70, 90, and 95 on five physics tests. The mean, median, and mode of his scores are given below. Mean = 83.4 median = 90 mode = 70 Which value best describes George's scores? Explain.
Answer:
mean; the average of George's scores is the mean = 83.4
Step-by-step explanation:
The value that best describes George's scores is the mean that has a value of 83.4.
What is the mean?
Mean is the average of a set of numbers. It is determined by adding the numbers together and dividing it by the total number. The mean makes use of all the data in the data set.
Mean = sum of the numbers / total number
(70+ 92 + 70 + 90 + 95) / 5 = 83.4.

Apply the problem-solving techniques to solve the following
problem.
Population decrease In 1990, a rural area had 1200 bird
species. If species of birds are becoming extinct at the rate of
1.5% per decade (10 years), how many bird species will there be
left in the
year
2020?
Answer:
By 2020, there will be 1,147 species of birds left
Step-by-step explanation:
The general model for an exponential decrease is;
y = I(1 - r)^t
where in this case;
y is the number of bird species at a particular decade from the initial
I is the number of birds initially at 1990
r is the decrease percentage which is 1.5% per decade ; 1.5% = 1.5/100 = 0.015
t in this case will be the number of decades after the initial
Mathematically, a decade is 10 years
The difference between 2020 and 1990 is 30
The number of decades in 30 years is 30/10 = 3
so t will be 3 here
Substituting these values into the equation, we have
y = 1200(1-0.015)^3
y = 1200(0.985)^3 = 1,146.8
To the nearest whole number, this is 1,147

A polygon has 6 sides. The exterior angles are 80 degrees, 56 degrees, 61 degrees, 43 degrees, 92 degrees, and (2 x) degrees. What is the value of x? x =
Answer:
14 degrees is right! just wanted to add some credibility(?) idrk. best of luck!
Step-by-step explanation:
The value of x in the polygon that has six sides(hexagon) is 14.
What is a hexagon?An hexagon is a polygon with six sides.
The exterior angles of the hexagon are as follows:
80°, 56°, 61°, 43°, 92°, and (2x)°.
Therefore,
sum of exterior angle = 360°
Hence,
80 + 56 + 61 + 43 + 92 + 2x = 360
332 + 2x = 360
2x = 360 - 332
2x = 28
x = 28 / 2
x = 14

A line that includes the point (2,7) has a slope of
–
8. What is its equation in point-slope form?
Use the specified point in your equation. Write your answer using integers, proper fractions, and improper fractions. Simplify all fractions.
Answer:
y - 7 = -8(x-2)
Step-by-step explanation:
The point slope form is: y-y1=m(x-x1)
From the information that was given, we know our two points: (2,7)
From here, we can fill in some of the missing information: y-y1=m(x-x1) → y - 7 = m(x-2)
Now I can't tell if you wrote down -8 or just 8, but just in case my answer isn't the right number.
The answer would either be: y - 7 = -8(x-2) [if you wrote down -8 as the slope]
OR
The answer would be: y - 7 = 8(x-2) [if you wrote down 8 as the slope]
