2(x - 9) = 10 can somebody solve this please using a method
Answer:
x=14
Step-by-step explanation:
Answer:
x = 14
Step-by-step explanation:
2(x - 9) = 10
2x - 18 = 10
add 18 o each side of the equation:
2x = 28
divide both sides by 2:
x = 14
Two numbers, x and y, have a sum of 8 and a difference of –14. A. Write a system of equations that can be used to determine the values of x and y. B. Solve the system of equations. Show your work.
Answer:
The system is:
x + y = 8
x - y = -14
And the solution is:
x = -3
y = 11
Step-by-step explanation:
We have two numbers x and y, such that:
x + y = 8 (the sum is equal to 8)
x - y = -14 (the difference is equal to -14)
This is the system of equations we need to solve.
To solve the system, we first need to isolate one of the variables in one of the equations, I will isolate x in the first equation:
x = 8 - y
Now we can replace this in the other equation to get:
(8 - y) - y = -14
8 - 2*y = -14
8 + 14 = 2*y
22 = 2*y
22/2 = y
11 = y
Now we can replace this in the equation "x = 8 - y"
To get:
x = 8 - 11 = -3
Then the solution to the system is:
x = -3 and y = 11

Answer:
The length of the radius is 2.95 units
The length of the radius of the circle is 2.95 units.
What is Circle?A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.
Given that blue segment below is a diameter of O
Diameter is five point nine.
We need to find the radius of the given circle.
Radius is equal to diameter by two
Radius= Diameter/2
Now put value of diameter in the above formula
Diameter = 5.9
Radius =5.9/2
=2.95
Hence, the length of the radius of the circle is 2.95 units.

a number times 12 is 72. which equation fits this statement?
Answer:
12x = 17
Step-by-step explanation:
So, this is a standard variable equation, so a number (I did x because I'm basic) times, multiplied by, whatever 12 = 72
So a number times 12 is 72 = 12x = 17
Now, if you wanted to actually solve this equation, you just have to do inverse operations:
17 ÷ 12 = 1.4167 (rounded)
So x = 1.4167

Answer:
A,C
Step-by-step explanation:
A triangle has two angles that measure 45 degrees and 35 degrees. What is the
measurement of the third angle?
Well, we know that a triangle's angles add up to 180°, so 45 + 35 + x = 180, and x = 100.
The third angle is 100.
Answer:
The measurement of the third angle is 100 degrees.
Step-by-step explanation:
Just add 45 + 35 which equals to 80. Every triangle's angles equal to 180 degrees so subtract 80 from 180. That equals 100 degrees.
Equation: 45+35=80
180-80=100
Hope this helps! :)

A circle is centered on point B. Points A, C and D lie on its circumference.
If ZABC measures 40°, what does ZADC measure?
Given:
A circle is centered on point B.
Points A, C and D lie on its circumference.
If [tex]m\angle ABC[/tex] measures 40°.
To find:
The [tex]m\angle ADC[/tex].
Solution:
Central angle theorem: According to this theorem, the central angle is equal to the twice of inscribed angle on the same intercepted arc.
In the given figure [tex]\angle ABC[/tex] is the central angle and [tex]m\angle ADC[/tex] is the inscribed angle on the same arc AC.
Using central angle theorem, we get
[tex]m\angle ABC=2m\angle ADC[/tex]
[tex]40^\circ=2m\angle ADC[/tex]
[tex]\dfrac{40^\circ}{2}=m\angle ADC[/tex]
[tex]20^\circ=m\angle ADC[/tex]
Therefore, the measure of angle ADC is 20°.

Area = (1/2)ADxBC
Area = (1/2)3x2
Area = (6/2)
Area = 3 square units

Which proportion correctly shows the relationship between the part, whole, and percent of a percent problem
Answer:
C. [tex]\frac{Part}{Whole} =\frac{Percent}{100}[/tex]
Step-by-step explanation:
A good way to think about it is this. You know that 1/2 is 50%. It's common knowledge.
In this case 1 is the Part and 2 is the whole
[tex]\frac{Part}{Whole} = \frac{1}{2} = .50[/tex]
So to get 50% in decimal form we would have to divide it by 100 to move the decimal over two places
[tex]\frac{Percent}{100} = \frac{50}{100} = .50[/tex]
Therfore,
[tex]\frac{1}{2} = \frac{50}{100}[/tex]
or
[tex]\frac{Part}{Whole} =\frac{Percent}{100}[/tex]
