Answer: The answer is 17
Step-by-step explanation:
First of you combine both 6x to get 12x and then you add the negatives to negative 24. you add 24 to the 180 and get 204 to isolate x. then you divide 204 by 12 and cancel it the 12 to isolate x and get x=17

In the diagram below of triangle HIJ, K is the midpoint of HJ and L is the
midpoint of IJ. If KL = -8x +96, and HI= -8x + 120, what is the measure
of KL?
H
L
Answer: 24
Step-by-step explanation: HI = 2 times KL
-8x + 120 = 2(-8x + 96)
-8x + 120 = -16x + 192
8x = 72
x = 9
KL = -8x + 96
KL = -8(9) + 96
KL = 24

A city in the Pacific Northwest recorded its highest temperature at 77 degrees Fahrenheit and its lowest temperature at 24 degrees Fahrenheit for a particular year. Use this information to find the upper and lower limits of the first class if you wish to construct a frequency distribution with 10 classes.
A. 24-29
B. 24-30
C. 24-28
D. 19-29
The upper and the lower limits of the class that we have here would be A. 24-29
How to find the upper and the lower limits of the classWe have to find the range of the temperature
This is given as maximum - minimum
= 77 - 24
= 53
width = range / n
width = 53 / 10
= 5.3
The approximate width can be given as 5.
The upper class would be the lower class + width
= upper class = 24 + 5 = 29
Hence the limit of the classes would be given as
A. 24-29

Twenty less than four times an mover is twenty one what is the number
Answer:
10.25
Step-by-step explanation:
Define the variable
Let x be the unknown number.
Therefore:
[tex]\begin{aligned}& \textsf{Four times a number}: \quad & 4x\\& \textsf{Twenty less than four times a number}: \quad & 4x-20\\& \textsf{Twenty less than four times a number is twenty one}: \quad & 4x-20=21\end{aligned}[/tex]
To find the number, solve the found equation for x:
[tex]\begin{aligned}\implies 4x-20&=21\\4x-20+20&=21+20\\4x&=41\\\dfrac{4x}{4}&=\dfrac{41}{4}\\x&=10.25\end{aligned}[/tex]
Therefore, the unknown number is 10.25.
As an improper fraction, this is ⁴¹/₄.
As a mixed number, this is 10 ¹/₄.
Answer:
x = 10.25
Step-by-step explanation:
Given that,
→ Twenty less than four times a number is twenty one.
The equation we form,
→ 4x - 20 = 21
Now the value of x will be,
→ 4x - 20 = 21
→ 4x = 21 + 20
→ x = 41/4
→ [ x = 10.25 ]
Hence, the number is 10.25.

Side of the given square room flooring is 12 foot
What is a square and its area?
A Square is a closed, two dimensional shape which has four sides and all four sides are equal and at 90 degree angle to each other .
As all four sides are equal, Let each of the side of a square is a
Area of the square is given by = a*a
Given that a designer paid $4 per square feet for a square flooring
Total amount spent by the designer = $600
Total area of flooring = total amount spent /rate of per unit area
= $600/$4 square foot =150 sq foot
Let the side of the given square flooring be x

An angle measures 111.4° more than the measure of its supplementary angle. What is the measure of each angle?
The measure of the supplementary angles are 34.3 and 145.7 degrees.
What are supplementary angles?Supplementary angles are those angles that sum up to 180 degrees.
In other words, two angles are Supplementary when they add up to 180 degrees.
Therefore, the angles measures 111.4° more than the measure of it's supplementary angle.
Hence,
let
x = measure of the other angle
x + x + 111.4 = 180
2x + 111.4 = 180
subtract 111.4 from both sides
2x + 111.4 - 111.4 = 180 - 111.4
2x = 68.6
divide both sides by 2
x = 68.6 / 2
x = 34.3
Other angle = 34.3 + 111.4 = 145.7°
Therefore, the measure of the supplementary angles are 34.3 and 145.7 degrees.

Based on the amount the winner receives, the interest rate to be compounded annually, and the number of years, the amount that should be invested to award the price is $35,720.80.
How much should be invested?The amount that should be invested is the present value of the $8,000 for the next 5 years. This amount would be the present value of an annuity due because constant payments that come at the beginning of a period are annuity dues.
Present value of annuity due = Annuity due x (Present value interest factor of annuity due, 6%, 5 years)

$850 at 7% compounded annually for 3 years how do you calculate earned interest?
Answer:
$191.29
Step-by-step explanation:
Use the formula
[tex]A = P(1 + \dfrac{r}{100})^n[/tex]
where P is amount deposited, A the accrued amount, n number of years and r the interest rate in % compounded annually
The division by 100 is necessary to convert r% to a decimal for calculations
We have P = 850, r = 7% and n = 3
Plugging these in we get
[tex]A = 850\cdot (1 + (\dfrac{7}{100})^3\\\\A= 850\cdot(1 + 0.07)^3\\A = 850\cdot1.07^3\\\A = \$1,041.29[/tex]
Interest = A - P = 1041.29 - 850 = $191.29

The graph of g is a translation 2 units left and 3 units up, followed by a reflection
in the y-axis of the graph of f(x) = x² - 2x.
Graph of g is a translation where g(x) = (x+2)^2 - 2x – 1
f(x) = x^2 - 2x
g(x) = f(x+2) + 3
Translation is a movement of the graph either horizontally parallel to the x-axis or vertically parallel to the y-axis. A translation is a geometric transformation that moves every point of a figure, shape or space by the same distance in a given direction. A translation can also be interpreted as the addition of a constant vector to every point, or as shifting the origin of the coordinate system. In a Euclidean space, any translation is an isometry.
Hence , g(x) = (x+2)^2 -2(x+2) + 3 = (x+2)^2 - 2x - 1. When we graph the equations, we can confirm that our answer is correct.

The equivalent expression of the given expression is 5n/4 -3/8
What is Algebraic expression ?
Algebraic expressions are the idea of expressing numbers using letters or alphabets without specifying their actual values. The basics of algebra taught us how to express an unknown value using letters such as x, y, z, etc. These letters are called here as variables. An algebraic expression can be a combination of both variables and constants. Any value that is placed before and multiplied by a variable is a coefficient.
Here, the given expression is :
(-2 ¹/₂n + ¹/₄) + (3 ³/₄n - 5/8)
simplifying the above expression by taking like considering like terms :
= -2 ¹/₂n + 3 ³/₄n + ¹/₄- 5/8
= (15/4)n - (5/2)n + (2-5)/8
= (15-10)n/4 -3/8
= 5n/4 -3/8

On a number line, B is between a and c. AB = 1/3ac
We may infer from the number line that A and B are separated by 8 units (AB).
Let AB stand for the separation between points A and B, and let AC stand for the separation between points A and C. Let B stand for the separation between points B and C. Hence:
Point B being halfway between A and C, we can infer:
AB + BC Equals AC (Postulated segment addition)
As a result, since the distance between points A and B is equal to 1/3 of AC:
AC/3 = AB = 1/3(AC)
But as shown in the accompanying image:
AC equals 16 – (–8) to 24 units.
Therefore:
