Answer:
x=12
Step-by-step explanation:
since they are supplementary they will have a sum of 180 degrees
The equation should look like this- (5x+4)+(4x+80)=180
after solving the equation- you get x=12
in order to see if that is correct you would plug in 12 where x is in our equation (5x+4)+(4x+80). which does equal 180 when 12 is plugged in
Therefore, 12 is your answer

please tell me the step process of this btw this is 7th-grade math its angle measurements I'm confused about the process pls help.
Answers
Answer:
Angle BDA is 90°
(2x + 3) + 55 = 90
2x + 3 + 55 = 90
2x + 58 = 90
2x = 90 - 58
2x = 32
x = 32/2
x = 16
Hence,
x=16
x=16Angle BDA is 90°.

Answer:
x = 1 ± [tex]\sqrt{6}[/tex]
Step-by-step explanation:
Given
2x² - 4x = 10 ( divide through by 2 )
x² - 2x = 5
Using the method of completing the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 1)x + 1 = 5 + 1
(x - 1)² = 6 ( take the square root of both sides )
x - 1 = ± [tex]\sqrt{6}[/tex] ( add 1 to both sides )
x = 1 ± [tex]\sqrt{6}[/tex] ← exact solutions

The equation for the charge (y) by Bethany's company for x months is ...
y = 5x +50
The equation for the charge (y) by Kami's company for x months is ...
y = 10x
The charges are equal when ...
y = y
5x +50 = 10x . . . . use the expressions for y
50 = 5x . . . . . . . . subtract 5x
10 = x . . . . . . . . . . divide by 5
The companies will charge the same for 10 months.

What is the measure of angle X, to the
nearest degree?
Answers
Answer:
56 degrees
Step-by-step explanation:
Assuming this is trigonometry, you use the tangent method. Which means in order to find the angle you put the adjacent side of what your finding and the opposite on top of it.
The equation is tan(angle)= 9/6
You multiply both sides by the arch of tangent and get
angle =tan^-1 (9/6)
I inserted it into my geometry calculator and got 56.30993247, I rounded to the nearest degree and got 56 degrees

Find the distance between the points A(10,-9) and B(8,7) round your answer to the nearest hundredth
Answers
Answer:
16.12 units
Step-by-step explanation:
These two points create a right triangle whose diagonal (hypotenuse) represents the desired distance.
Going from B(8, 7) to A(10, -9) involves two steps: Moving 2 units to the right from B(8, 7) to A(10, -9), and moving 16 steps down from B(8, 7) to A(10, -9).
Thus, the horizontal side of the triangle in question has length 2 units and the vertical side 16 units.
The length of the diagonal (which is the desired distance) is then
|AB| = +√(2^2 + 16^2) = +√(4 + 256) = +√260
To the nearest hundredth, this is |AB| = 16.12 units

According to the Triangle Inequality Theorem, any 2 sides of the triangle must always be more than the third. Here, we can see that the theorem is violated because 11 + 11 < 25. Therefore, it is not a legitimate Triangle.

The sum of 7.2 and a number is 10.
First, write an equation to describe the situation.
7.2 + 3 = 10
What is the number?
The number is
Answers
Answer:
7.2 + x = 10
Step-by-step explanation:
I did 7.2 + x = 10 Because there was suspose to be a number in between
that we do not know so you have to put 7.2 + x = 10
Then... For the next question (The same question but asking the number in between) The second Question you do 7.2 - 10 and you get 2.8
The equation to describe the situation when the sum of 7.2 and a number is 10 is given so it is 7.2 + x = 10.
Calculation of an equation:Since
The sum of 7.2 and a number is 10.
So here we assume the number be x
So,
7.2 + x = 10
x = 2.8
hence, The equation to describe the situation when the sum of 7.2 and a number is 10 is given so it is 7.2 + x = 10.
