Answer:
The value of x is 84 and the remaining angles are: 76° and 86°
Step-by-step explanation:
Given three angles are
18
x-8
and
x+2
We have to find the angles and for that we have to find the value of x
As we know that the sum of internal angles of a triangle is 180°
So,
[tex]18+(x-8)+(x+2) = 180\\18+x-8+x+2 = 180\\2x+12 = 180\\2x = 180-12\\2x = 168\\x = \frac{168}{2}\\x = 84[/tex]
And the angles are:
x-8 = 84-8 = 76
x+2 = 84+2 = 86
Hence,
The value of x is 84 and the remaining angles are: 76° and 86°

Four times the sum of a number and 3 is the same as the sum of two times the number and 8. Find the number.
Answer:
Step-by-step explanation:
4 (x + 3) = 2x + 8 <----"four times the sum of a number and three is equal to eight more than twice the number."
Second, we want to solve the equation:
4 (x + 3) = 2x + 8
4x + 12 = 2x + 8
2x + 12 = 8 <-------subtract 2x from both sides of the equation.
2x = -4 <-------subtract -12 from both sides
x = -2 <-------divide both sides by 2 which leaves a negative answer
Third, we want to check the answer by substituting the value of -2 for x in the original equation.
4 (x + 3) = 2x + 8
4 (-2 +3) = 2(-2) + 8
-8 + 12 = -4 + 8
4 = 4
4 (x + 3) = 2x + 8 <----"four times the sum of a number and three is equal to eight more than twice the number."
Second, we want to solve the equation:
4 (x + 3) = 2x + 8
4x + 12 = 2x + 8
2x + 12 = 8 <-------subtract 2x from both sides of the equation.
2x = -4 <-------subtract -12 from both sides
x = -2 <-------divide both sides by 2 which leaves a negative answer
Third, we want to check the answer by substituting the value of -2 for x in the original equation.
4 (x + 3) = 2x + 8
4 (-2 +3) = 2(-2) + 8
-8 + 12 = -4 + 8
4 = 4

what is x+3= - (-x+ ___ )
Answer:
-3
Step-by-step explanation:
Note the right side of the equation. There is a negative sign outside of the parenthesis. Distribute the negative sign to all terms within the parenthesis:
x + 3 = - (-x + __)
x + 3 = x - ___
Note:
1) When multiplying a negative and positive together, the answer will be negative
2) When multiplying a negative and negative together, the answer will be positive:
x + 3 = x - ___
Note the equal sign, this means that the two side of the equation must equal. This means that the only answer choice is -3:
x + 3 = x - (-3)
x + 3 = x + 3 (True)

Answer:
3y - x = 3
Step-by-step explanation:
The slope intercept form of the equation is expression is y = mx+c
m is the slope
c is the y inercept
From the graph
c = 1
Using the coordinates (-3, 0) and (0, 1)
m = 1-0/0-(-3)
m = 1/3
Get the required equation
y = 1/3x + 1
Multiply through by 3
3y = x + 3
3y - x = 3
Hence the required equation is 3y - x = 3

Answer:
B. 86 degrees
Step-by-step explanation:
Given the following angles
m∠NOP = 24
m∠NOQ = 110
Required
m∠POQ
The following addition postulate is true for the angles
m∠NOQ = m∠NOP + m∠POQ
m∠POQ = m∠NOQ -m∠NOP
Substitute the angles given into the formula:
m∠POQ = 110 - 24
m∠POQ = 86°
Hence the measure of angle POQ is 86 degrees

Two friends went to buy fireworks to celebrate new years eves. One friend bought 6 rockets and 11 bombs for $36.50. The other one bought 14 rockets and 8 bombs for $41. What was the cost of one rocket? (solve with system of equations)
Answer:
Cost of one rocket = $1.5
Step-by-step explanation:
Given:
6 rockets and 11 bombs cost = $36.50
14 rockets and 8 bombs cost = $41
Find:
Cost of one rocket
Computation:
Cost of one rocket = x
Cost of one bomb = y
So,
6x + 11y = 36.50.....eq1
14x + 8y = 41......eq2
From eq1
y = [36.50 - 6x]/11
From eq2
14x + 8y = 41
14x + 8[36.50 - 6x]/11 = 41
x = 1.5
Cost of one rocket = $1.5

What is the value of g(f(2))?
Answer: D.31
Step-by-step explanation: 4(2)^3-10 = 22 then take that into 3(22)-4/2 = 31
The value of the composition of function g ( f ( 2 ) ) = 31
What is Composition of functions?Evaluation of a function at the value of another function is known as Composition of function. A function composition is a process in which two functions, f and g, form a new function, h, in such a way that h(x) = g(f(x)). This signifies that function g is being applied to the function x. So, in essence, a function is applied to the output of another function.
Given data ,
Let the first function be represented as f ( x )
Now , the value of f ( x ) is
f ( x ) = 4x³ - 10
Let the second function be represented as g ( x )
Now , the value of g ( x ) is
g ( x ) = ( 3x - 4 ) / 2
The composition of function is g ( f ( 2 ) )
Now , the value of f ( 2 ) = 4 ( 2 )³ - 10
f ( 2 ) = 32 - 10 = 22
And , the value of g ( 22 ) = [ 3 ( 22 ) - 4 ] / 2
g ( 22 ) = ( 66 - 4 ) / 2g ( 22 ) = 62 / 2 = 31
Hence , the value of the function is g ( f ( 2 ) ) = 31

if the base area of a cylinder is 15.6 square centimeters and the height is four centimeters what is the volume of the cylinder?
Answer:
Volume of the cylinder = 62.4 cm³
Step-by-step explanation:
Volume of a cylinder = area of base × height of the cylinder
Area of base = 15.6 square centimeters
Height of the cylinder = 4 centimeters
Volume of a cylinder = area of base × height of the cylinder
= 15.6 cm² × 4 cm
= 62.4 cm³
Volume of the cylinder = 62.4 cm³
