Which system of equations canbe used to determine the cost per pound of walnuts x, and the cost per pound ofalmonds, y?F 2x - 4y = 284x + 3y = 31G 2x + 4y = 284x + 3y = 31H 2x + 4y = 314x + 3y = 28) 4x + 3y = 282x + 4y = 31
Let the selling price for walnuts be x and the selling price for the almonds be y.
On the first day, Erick sold 2 pounds of walnuts and 4 pounds of almonds for $28. This implies that

The line segment with end points (-8, -7), (-7, -8).
That implies,
[tex]\begin{gathered} Midpoint=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2}) \\ =(\frac{-8+(-7)}{2},\frac{-7+(-8)}{2}) \\ =(\frac{-8-7}{2},\frac{-7-8}{2}) \\ =(-\frac{15}{2},-\frac{15}{2}) \end{gathered}[/tex]Hence, the midpoint of the line segment is (-15/2, -15/2).
I would like to know the formula that was used to get 120 cm
The given figure is a 2d representation of a 3d figure. If we wrap this figure, we get a building block.
In the figure below, the unknown edges are written:
Now, we have to find the area of all the polygons given in the figure. It consists of two same triangles and three different rectangles.
The area of the two triangles is given below:
[tex]\begin{gathered} A=2\times\frac{1}{2}\times\text{base}\times\text{height} \\ =\text{base}\times\text{height} \\ =3\times4 \\ =12 \end{gathered}[/tex]Thus, the area of two triangles is 12 cm^2.
We know that the area of a rectangle is length times width. Now, the area of three rectangles is given below:
[tex]\begin{gathered} A=9\times5+9\times4+9\times3 \\ =45+36+27 \\ =108 \end{gathered}[/tex]Thus, the area of three rectangles is 108 cm^2.
So, the total area is 12 + 108 = 120 cm^2.

D - Add, Subtract, Multiply, and Divide Integer A submarine Is at a depth of 350 feet below sea level. It makes the following moves. • First, it goes down 150 feet. • Next, it goes up 132 feet. • Then, it goes down 179 feet. • Finally, it goes down 145 feet. Which statement describes its current depth? A It is 692 feet below sea level, because -350 + (-150) + 132 + (-179) + (-145) = -692. B It is 8 feet below sea level, because 350 + (-150) + 132 + (-179) + (-145) = 8. c It is 256 feet below sea level, because 350 + (-150) +..(-132) + (-179) + (-145) = -256. D It is 342 feet below sea level, because 150 132 179 145 = 342. AI B ci D
We have the next information
A submarine Is at a depth of 350 feet below sea level means -350
First, it goes down 150 feet. means -150
Next, it goes up 132 feet. means +132
Then, it goes down 179 feet. means -179
Finally, it goes down 145 feet means -145
then we have the next operations
-350+(-150)+132+(-179)+(-145)=-692
The sing minus means that It is below the sea level
therefore the correct choice is
A It is 692 feet below sea level, because -350 + (-150) + 132 + (-179) + (-145) = -692.
If John Carlo has 4 times as many nickels as quarters and they have a combined value of 270 cents, how many of each coin does he have?
There 6 quarters and 24 nickels of each coins that John Carlo has.
How to calculate for the number of each coins.There are 5 cents in a nickel and 25 cents in a quarter. Let us represent the number of quarters as x so that the number of nickels that John Carlo has will be 4x.
Thus, 4x(5 cents) + x(25 cents) = 270 cents
20x cents + 25x cents = 270 cents
45x cents = 270 cents
divide through by 45
x = 270/45
x = 6
and thus there are 4(6) = 24 nickels.
Therefore, John Carlo has 6 quarters and 24 nickels each of coins.

What is rectangle?
A rectangle is a sort of quadrilateral with parallel sides that are equal to one another and four vertices that are all 90 degrees apart. Because of this, it is also known as an equiangular quadrilateral. Because the opposite sides of a rectangle are equal and parallel, it can also be referred to as a parallelogram.let width = x
length = x + 3
area = 22
area of rectangle = l * w
22 = x * ( x + 3 )
22 = x² + 3x
x² + 3x - 22 = 0
x = -3 ± √3² - 4 .1 (-22)/2.1
x = -3 ± √9 + 88/2

A solution to a system of linear equations in two variables is an ordered pair that makes BOTH equations true.
When is the system of equations is said to be consistent?
If there is at least one combination of values for the unknowns that satisfies each equation in the system—that is, makes each equation hold true as an identity—then a system of equations, whether linear or nonlinear, is said to be consistent.
When is the system of equations is said to be non-consistent?
If there isn't a set of values for the unknowns that solves every equation, then the system of equations is said to be inconsistent.
Ex: Consider a system of linear equations:
x+3y=6
x=-3y+6 …..(1)

ANSWER:
s=l-r l solve for r ty for your answer
The modulus of |-r| means that it is an absolute value. Therefore, the answer is "s".
What is the absolute value function?The absolute value function is defined by the following piecewise rule, depending on the input of the function:
|x| = x, x ≥ 0.
|x| = -x, x < 0.
It measures the distance of a point x to the origin, thus, |-2| = |2| = 0, and has vertex(turning point) at (0,0). Then the range is from the y-coordinate of the vertex to positive infinity.
WE have given as s=l-r l
When we add a positive or negative number in between the lines then; it is;
|-r| goes through = -r = -s
|-r| goes through = r = s
The modulus of |-r| means that it is an absolute value. Therefore, the answer is "s".

An architect makes a model of a new house. The model shows a tile patio in the backyard. In the model, each tile has length 2/3 in. and width 1/2. The actual tiles have length 1/2 ft and width 3/8 ft. What is the ratio of the length of a tile in the model to the length of an actual tile? What is the ratio of the area of a tile in the model to the area of an actual tile? Use pencil and paper. Describe two ways to find each ratio. The ratio of the length of a tile in the model to the length of an actual tile is?
Ratio of the length of a tile in model to length of actual tile is 1/9 and Ratio of Area of tile to area of actual tile is 1/ 81
Given,
Length of each tiles = 2/3 in
Width of each tiles = 1/2 in
The actual tiles have length = 1/2 ft = 6 in {1 foot = 12 inch }
Width of actual tiles = 3/8 ft = 4.5 in
Ratio of length of tile in the model to the length of an actual tile =
length of tile / length of an actual tile
= [tex]\frac{2/3}{6} = \frac{1}{9}[/tex]
Area of tiles = area of rectangle = length × width
= 2/3 × 1/2
= 1/3 in²
Area of actual tile = 6 × 4.5 = 27 in²
Ratio of the area of a tile in the model to the area of an actual tile =
Area of tile / area of actual tiles
= [tex]\frac{1/3}{27} = \frac{1}{81}[/tex]
Another way of finding ratio is by Dilation ,
Ratio of lengths = 1 / 9
according to the property of dilation,
Ratio of area of tiles to area of actual tiles = (1/9)² = 1/81

The ratio of the heights of similar cones is 5:2. If the base area of the small cone is 64pi cm^2, find the base area of the large cone. Thanks!
Answer: 400π
Explanation:
From the information given, the ratio of the heights is 5:2. This means that the scale factor is 5:2. This means that the ratio of the areas is
(5/2)^2 = 25/4 = 25:4
Thus,
base area of large cone/base area of small cone = 25/4
Given that base area of small cone is 64π, it means that
base area of large cone/64π = 25/4
By cross multiplying,
base area of large cone = 25/4x 64π
base area of large cone = 400π
