Answer:
No Solution
Step-by-step explanation:
Substituting y = -4x into the first equation, we get:
8x + 5(-4x) = 24(-4x)
Simplifying this equation, we get:
8x - 20x = -96x
Dividing both sides by -12x, we get:
-4/3 = -96
This equation has no solution, which means that the system of equations is inconsistent and does not have a unique solution.
Therefore, the system of equations cannot be solved to find the values of x and y.

_____________
A scale model of the Sergeant Floyd Monument is 10
inches tall. The actual monument is 100 feet tall. What is
the scale of the model? What is the scale factor?
Answer:
1/120 or 120
Step-by-step explanation:
Actual monument is 1200 inches tall so that means if we want to find the scale of the model then we do 10/1200 so that = 1/120 or if we are finding the scale factor from the model to the actual then it is 120.
Each equation represents a proportional relationship. Choose the equations for which the constant of proportionality is 1/4
.
A) y = 4x
B) y = 0.25x
C) 4y = x
D) 32y = 8x
E) 1/4y = 2x
Answer: E)1/4y=2x
Step-by-step explanation:
The constant of proportionality represents the ratio between the dependent and independent variables in a proportional relationship. If the constant of proportionality is 1/4, it means that the dependent variable is one-fourth the value of the independent variable.
So, we need to determine which equations have a constant of proportionality of 1/4:
A) y = 4x
The constant of proportionality in this equation is 4, not 1/4.
B) y = 0.25x
The constant of proportionality in this equation is 1/4.
C) 4y = x
The constant of proportionality in this equation is 1/4, since we can rewrite it as y = 1/4x.
D) 32y = 8x
We can simplify this equation by dividing both sides by 8:
4y = x
The constant of proportionality in this equation is 1/4.
E) 1/4y = 2x
We can rewrite this equation as:
y = 8x
The constant of proportionality in this equation is 8, not 1/4.
Therefore, the equations for which the constant of proportionality is 1/4 are B), C), and D).
Answer:
B, C, D
Step-by-step explanation:
You want to identify the equations that have a constant of proportionality of 1/4.
Proportional relationA proportional relationship can be written in the form ...
y = kx
where k is the constant of proportionality.
You want to identify those relations that are equivalent to this with k=1/4.
ChoicesA) y = 4x . . . . . k = 4 ≠ 1/4
B) y = 0.25x . . . . . k = 0.25 = 1/4
C) 4y = x ⇒ y = 1/4x . . . . . k = 1/4
D) 32y = 8x ⇒ y = 8/32x = 1/4x . . . . . k = 1/4
E) 1/4y = 2x ⇒ y = 2/(1/4)x = 8x . . . . . k ≠ 1/4
The relations with a constant of proportionality of 1/4 are B, C , D.

Answer:
See below.
Step-by-step explanation:
For this problem, we are asked to find equivalent expressions.
We should use the Distributive Property.
What is the Distributive Property?
The Distributive Property is a property that allows us to multiply the number outside of the parentheses into the numbers inside the parentheses. Think of the Distributive Property in the form of x (y + z); We multiply x with y and z.
Since we know what the Distributive Property is, we can begin finding equivalent expressions.
Let's start by distribution:
[tex]3x+3(x+y)\\3x + 3x + 3y\\6x + 3y[/tex]
A is a correct option.
Let's check B and C.
Distribute:
[tex]3(x+x+y)\\3x+3x+3y\\6x+3y[/tex]
B is a correct option.
Distributing isn't needed for expression C.
[tex]3xy\neq 6x + 3y[/tex]
C is an incorrect option.
A and B are the correct options.

Sammy went on a bike ride. He rode his bike 9.5 miles Monday,100.1 miles Tuesday, 50.4 miles Wednesday and 32.3 miles Thursday. How many miles did he ride in total?
Answer: 192.3
Step-by-step explanation:
First, what I would do is add all the whole numbers only.
9 + 100 + 50 + 32 = 191
Next, you would add the decimals like this:
.5 + .1 + .4 + .3 = 1.3
191 + 1.3 = 192.3
Hope this helps :)

Answer: the question I don’t think is written right
Step-by-step explanation:
Susan the author owns a independent bookstore. On Monday,she sells 500 books for $30 each. On Tuesday she sells 50 books for $60 each. On Wednesday she sells 300 books for $80 each. Thursday she sells 400 books for $70 each. Friday she sells 800 books for $800 each. How much money did she make those 5 days?
Answer:
She made $710,000.
Step-by-step explanation:
First, let's multiply how many books she sells per day to the price for each of them. 500x30= 15000, 50x60=3000, 300x80=24000, 400x70=28000, and lastly, 800x800=64000. Next, add up all the numbers to get your total of $710,000!

20 points and guaranteed brainliest!! A rectangular prism is 3 inches long, 5 inches wide, and has a height of 6 inches. What is its surface area?
90 in 2
120 in 2
126 in 2
63 in 2
Answer: 126 in ^2
Step-by-step explanation:
The surface area of a rectangular prism is given by the formula:
Surface Area = 2lw + 2lh + 2wh
where l, w, and h are the length, width, and height of the rectangular prism, respectively.
Substituting the given values, we get:
Surface Area = 2(3)(5) + 2(3)(6) + 2(5)(6)
Surface Area = 30 + 36 + 60
Surface Area = 126 square inches
Therefore, the surface area of the rectangular prism is 126 in^2.
Answer: 126!!

Step-by-step explanation:
A triangle undergoes a sequence of transformations. First, the triangle is dilated by a scale factor of 1/3 about the origin. Then the triangle is reflected over the x-axis. Finally, the triangle is translated left 3 units and up 2 units.
How does the image triangle compare to the pre-image triangle?
PLEASE HELP ASAP!!!!! 90 POINTS GUYS!!!!!
Answer: Your welcome!
Step-by-step explanation:
The final coordinates of the triangle after these transformations are (-4, -4), (-4, -1), and (-1, -4).
The triangle was dilated by a scale factor of 1/3, which means that the lengths of each side were divided by 3. The triangle was then reflected over the x-axis, which means that the y-coordinates of each vertex were multiplied by -1. Finally, the triangle was translated left 3 units and up 2 units, which means that 3 was subtracted from each x-coordinate and 2 was added to each y-coordinate. This resulted in the final coordinates of (-4, -4), (-4, -1), and (-1, -4).
Factor this expression completely and then place the factors in the proper location on the grid.

Answer:
A: x
B: 24
C: -15x
D: -14x
Step-by-step explanation:
This is a system of equations problem. The easiest way to find the answers to each of the given blanks is to seek a way to allow for terms within each equation to cancel out when added or subtracted from each other. We can see that within the Y column, they share the least common multiple of 10. In order for the top equation to yield a value of 10y, we must multiply the entirety of it by 2. By doing this we will get x + 10y = 24. Hence, A = x and B = 24. In order to yield a value of | 10y | in the lower equation, we must multiply the entirety of it by -5 (the negative is due to the fact that the value must be -10 in order to cancel out with 10y in the first equation upon adding them together). Once multiplied, we should get -15x - 10y = 200. The subtraction symbol between -15x and 10y can be seen as attached to 10y. These equations combined after multiplication will leave one to be solved for x --> -14x = 224. Therefore, C = -15x and D = -14x.
