Answer:
Area of Rectangle A
![Area = 4x^2](https://tex.z-dn.net/?f=Area%20%3D%204x%5E2)
Area of Rectangle B
![Area = 2x^2](https://tex.z-dn.net/?f=Area%20%3D%202x%5E2)
Fraction
![Fraction =\frac{2}{3}](https://tex.z-dn.net/?f=Fraction%20%3D%5Cfrac%7B2%7D%7B3%7D)
Step-by-step explanation:
From the attached, we understand that:
The dimension of rectangle A is 2x by 2x
The dimension of rectangle B is x by 2x
Area of rectangle is calculated as thus;
![Area = Length * Breadth](https://tex.z-dn.net/?f=Area%20%3D%20Length%20%2A%20Breadth)
Area of Rectangle A
![Area = 2x * 2x](https://tex.z-dn.net/?f=Area%20%3D%202x%20%2A%202x)
![Area = 4x^2](https://tex.z-dn.net/?f=Area%20%3D%204x%5E2)
Area of Rectangle B
![Area = x * 2x](https://tex.z-dn.net/?f=Area%20%3D%20x%20%2A%202x)
![Area = 2x^2](https://tex.z-dn.net/?f=Area%20%3D%202x%5E2)
Area of Big Rectangle
The largest rectangle is formed by merging the two rectangles together;
The dimension are 3x by 2x
The Area is as follows
![Area = 2x * 3x](https://tex.z-dn.net/?f=Area%20%3D%202x%20%2A%203x)
![Area = 6x^2](https://tex.z-dn.net/?f=Area%20%3D%206x%5E2)
The fraction of rectangle A in relation to the largest rectangle is calculated by dividing area of rectangle A by area of the largest rectangle;
![Fraction = \frac{Rectangle\ A}{Biggest}](https://tex.z-dn.net/?f=Fraction%20%3D%20%5Cfrac%7BRectangle%5C%20A%7D%7BBiggest%7D)
![Fraction =\frac{4x^2}{6x^2}](https://tex.z-dn.net/?f=Fraction%20%3D%5Cfrac%7B4x%5E2%7D%7B6x%5E2%7D)
Simplify
![Fraction =\frac{2x^2 * 2}{2x^2 * 3}](https://tex.z-dn.net/?f=Fraction%20%3D%5Cfrac%7B2x%5E2%20%2A%202%7D%7B2x%5E2%20%2A%203%7D)
![Fraction =\frac{2}{3}](https://tex.z-dn.net/?f=Fraction%20%3D%5Cfrac%7B2%7D%7B3%7D)
Given:
The inequality is
![x+19\leq 23](https://tex.z-dn.net/?f=x%2B19%5Cleq%2023)
To find:
The value of x and then graph on the number line.
Solution:
We have,
![x+19\leq 23](https://tex.z-dn.net/?f=x%2B19%5Cleq%2023)
Subtracting 19 from both sides, we get
![x+19-19\leq 23-19](https://tex.z-dn.net/?f=x%2B19-19%5Cleq%2023-19)
![x\leq 4](https://tex.z-dn.net/?f=x%5Cleq%204)
It means all the real values of x which are less than or equal to 4 are in the solution set. So, an arrow approaches towards left from x=4 as shown in the below figure.
Answer:
there are 8 ounces in a half pound
Step-by-step explanation:
Answer:
The solution is x = -2, y = -3
Step-by-step explanation:
Let's start with the equation 3x + y = -9
Substitute the y for 5x+7 seen in the second equation
Now you have 3x + (5x+7) = -9
Lets solve:
Let's add the x's
Now we have 8x + 7 = -9
Substracy seven from each side
Now we have 8x = -16
Now let's divide 8 on each side
Now we have x = -2
Now lets plug in -2 to the second equation
The second equation is y = 5x+7
When we plug in -2 we get y=5(-2)+7
We multiply
We now have y = -10+7
Add
y = -3
The solution is x = -2, y = -3
