Amaya used these steps to solve the equation 8x+4=9+4(2x−1). Which choice describes the meaning of her result, 4=5?
Answer:
No value of x makes the equation true.
Step-by-step explanation:
Here are the choices which are missing in the question:
a) Amaya made a mistake because 4 is not equal to 5
b) No value of x make the equation true.
c) All value of x make the equation true.
d) The solution is x= 4 or 5
Given equation is [tex]8x+4=9+4(2x-1)[/tex]
Now, solving the equation:
[tex]8x+4=9+4(2x-1)[/tex]
distributing 4 with both 2x and -1
⇒[tex]8x+4= 9+8x-4[/tex]
⇒[tex]8x+4= 5+8x[/tex]
Subtracting both side by 8x
∴ 4=5
The result indicate that equation has the same result and x has no value.
Answer:
No values of x make the equation true.

Find the other endpoint given one endpoint (-1,6) and the midpoint is (4,2)
Answer:
The required points of the given line segment are ( 9, - 2 ).
Step-by-step explanation:
Given that the line segment AB whose midpoint M is ( 4, 2 ) and point A is ( - 1, 6), then we have to find point B of the line segment AB -
As we know that-
If a line segment AB is with endpoints ( [tex]x_{1}, y_{1}[/tex] ) and ( [tex]x_{2}, y_{2}[/tex] )then the mid points M are-
M = ( [tex]\frac{ x_{1} + x_{2} }{2}[/tex] , [tex]\frac{ y_{1} + y_{2}}{2}[/tex] )
Here,
Let A ( - 1, 6 ), B ( x, y ) with midpoint M ( 4, 2 ) -
then by the midpoint formula M are-
( 4, 2 ) = ( [tex]\frac{ - 1 + x}{ 2}[/tex] , [tex]\frac{ 6 + y}{2}[/tex] )
On comparing x coordinate and y coordinate -
We get,
( [tex]\frac{ -1 + x}{2}[/tex] = 4 , [tex]\frac{ 6 + y}{2}[/tex] = 2)
( - 1 + x = 8, 6 + y = 4)
( x = 8 + 1, y = 4 - 6 )
( x = 9, y = -2 )
Hence the required points A are ( 9, - 2 ).
We can also verify by putting these points into Midpoint formula.
What makes a trapezoid an isosceles trapezoid?
Answer:
A: Its legs are congruent
Step-by-step explanation:
A trapezoid is a quadrilateral with exactly one pair of parallel sides. In a trapezoid the parallel sides are called bases. A pair of angles that share a base as a common side are called a pair of base angles. A trapezoid with the two non-parallel sides the same length is called an isosceles trapezoid.
An isosceles trapezoid is a trapezoid with two congruent sides and congruent base angles.
Explanation:An isosceles trapezoid is a trapezoid that has two congruent sides. In other words, the two non-parallel sides of an isosceles trapezoid are equal in length. The base angles of an isosceles trapezoid are also congruent. The parallel sides of an isosceles trapezoid are not equal in length.
For example, if a trapezoid has sides AB = 6 cm, BC = 5 cm, CD = 4 cm, and DA = 5 cm, then it is an isosceles trapezoid because sides BC and DA are congruent.

There are 30 chairs in the band room mr avery wants to have the same number of chairs in each row there must be more than 1 row and the number of chairs in each row must also be greater than the number of rows explain how mr avery could arrange the chairs
Final answer:
Mr. Avery can arrange the 30 chairs in 5 rows of 6 chairs each or 3 rows of 10 chairs each to satisfy the conditions of having more than one row and the chairs per row being greater than the number of rows.
Explanation:
Mr. Avery can arrange the 30 chairs in the band room in multiple configurations but must satisfy two conditions: there must be more than one row and the number of chairs in each row must be greater than the number of rows. To find such arrangements, we can look for factors of 30 that adhere to these conditions. One possible arrangement is 5 rows with 6 chairs in each row. This satisfies the conditions because there are more than one row, and the number of chairs per row (6) is greater than the number of rows (5).
Another possible arrangement could be 3 rows with 10 chairs each. Here, the condition is also met since there are more than one row and the number of chairs per row (10) is greater than the number of rows (3). Mr. Avery must ensure there's enough space to move around, so he may need to rearrange the chairs to provide adequate pathways between rows.

To be labeled as a jumbo egg, the egg is supposed to weight 2.5 oz. However, when Desmond buys a carton of jumbo eggs, the weight of one is 2.4 oz. What is the percent error?
(Explain in a detailed way on how you got your answer)
The percent error is 4.17 %
Solution:
To be labeled as a jumbo egg, the egg is supposed to weight 2.5 oz
When Desmond buys a carton of jumbo eggs, the weight of one is 2.4 oz
To find: percent error
Percent error is the difference between a measured and known value, divided by the known value, multiplied by 100%
[tex]\% \text { error }=\frac{\text {approximate value}-\text {exact value}}{\text {exact value}} \times 100[/tex]
Here approximate value = 2.5 oz and exact value = 2.4 oz
[tex]\% \text { error }=\frac{2.5-2.4}{2.4} \times 100\\\\\% \text { error }= \frac{0.1}{2.4} \times 100 = 4.17[/tex]
Therefore percent error is 4.17 %
Find the greatest common factor of 10, 30,10,30,10, comma, 30, comma and 454545.
Answer:
GCF = 5
Step-by-step explanation:
Given:
The numbers are given as:
10, 30 and 45
A factor of a number is a number by which the given number is evenly divisible.
Example: 2 is a factor of 4 as [tex]4\div 2 =2[/tex]. So, 4 is evenly divisible by 2 and hence 2 is a factor of 4.
Now, factors of 10 = 1, 2, 5, 10.
Factors of 30 = 1, 2, 3, 5, 6, 10, 15, 30.
Factors of 45 = 1, 3, 5, 9, 15, 45.
So, the greatest common factor in all the three numbers is 5.
Hence, the greatest common factor of 10, 30 and 45 is 5.

So here the decimal part is not repeating. So [tex]\frac{11}{40}[/tex] does not represent repeating decimal
Option 2
[tex]\frac{3}{25} =0.12[/tex]
So here the decimal part is not repeating. So [tex]\frac{3}{25}[/tex] does not represent repeating decimal
Option 3
[tex]\frac{25}{48} = 0.52083333333[/tex]
So here in decimal part "3" is repeating and goes on forever
So [tex]\frac{25}{48}[/tex] represents repeating decimal
Option 4
[tex]\frac{7}{32} = 0.21875[/tex]
So here the decimal part is not repeating. So [tex]\frac{7}{32}[/tex] does not represent repeating decimal

Benson played 12 games of trivia. He had
a perfect score on every game and received
35 bonus points per game. He earned a
total of 1,260 points. How many points did
he earn per game not including the
bonus points?
Benson earned 70 points per game not including the bonus points.
Step-by-step explanation:
Given,
Games of trivia played = 12
Bonus points received per game = 35 points
Bonus points for 12 games = 35*12 = 420 points
Total points earned = 1260 points
Points earned in games = Total points - bonus points
Points earned in games = 1260 - 420 = 840 points
As he scored 840 points in 12 games, therefore,
12 games = 840 points
1 game = [tex]\frac{840}{12} = 70\ points[/tex]
Benson earned 70 points per game not including the bonus points.

The area of a 2D form is the amount of space within its perimeter. The width of the rectangle is 10/7 miles.
What is an area?The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm2, m2, and so on. To find the area of a square formula or another quadrilateral, multiply its length by its width.
The area of a rectangle is the product of its length and its width, therefore, the width of the rectangle can be written as,
Area = Length × Width
Width = Area / Length
Given the area of the rectangle is 6/7 square miles, while the length of the rectangle is 3/5 miles, therefore, the width of the rectangle is,
Width = (6/7)/(3/5)
Width = (6×5)/(7×3) = 10/7

Circle A and circle B are congruent. CD is a cord of both circles. if AB = 24 inches in the radius is 13 inches how long is CD A.10in B.26in C.12in D.9in
Option A
Length of CD is 10 inches
Solution:
The diagram is attached below
Given that, Circle A and circle B are congruent
CD is a cord of both circles
AB = 24 inches
Radius = 13 inches
To find: length of CD
Draw a straight line connecting A and C
AC represents the radius of circle. Also given that radius is 13 inches, So AC = 13 inches
Given in question that AB = 24 inches
Therefore from figure, AO = AB/2 = 24/2 = 12
AO = 12
Let "b" be the length of CO
Therefore, CD = CO + OD = b + b
AOC forms a triangle, so we can use pythogoras theorem
Pythagorean theorem, states that the square of the length of the hypotenuse is equal to the sum of squares of the lengths of other two sides of the right-angled triangle.
By above definition for triangle AOC
[tex]AC^2 = AO^2 + OC^2[/tex]
Substituting AC = 13 and AO = 12 and OC = b
[tex]13^2 = 12^2 + b^2\\\\b^2 = 169 - 144\\\\b^2 = 25\\\\b = 5[/tex]
Thus length of CD is:
CD = b + b = 5 + 5 = 10
Thus length of CD is 10 inches
