Answer:
The value of n = 4 and
The value of x =
Step-by-step explanation:
Method I:
As given, 12x -20=n (3x-5) .........(1)
Firstly , take 12x - 20
As 12x - 20 can be written as 4(3x - 5)
∴ equation (1) becomes
4(3x - 5) = n (3x-5)
Divide the equation by (3x-5) , we get
4 = n
Method II:
As given, 12x -20=n (3x-5)
⇒12x - 20 = 3nx - 5n
⇒12x - 3nx = 20 - 5n
⇒3x(4 - n) = 5( 4 - n)
Divide the equation by (4-n) , we get
3x = 5
⇒ x =
∴ we get
n = 4 and x =
Now, check that value of n and x satisfies the equation or not
12() - 20 = 4( 3(
) - 5)
⇒4(5) - 20 = 4(5 - 5)
⇒20 - 20 = 4(0)
⇒ 0 = 0
Hence , we get
The values of x and n satisfies the equation
so, we get
n = 4 and x =
Answer:
Areas of the colored parts are equal
Step-by-step explanation:
Given Mauricio divided two identical rectangles into equal parts.
Now given Mauricio colored one part of each rectangle. we have to tell about the true statement of colored parts.
Two identical rectangles means the rectangle having equal areas. He divides these two into equal parts and shaded one of each part
Let area of rectangle is x
∴ Colored part area = → (1)
Similarly, other rectangle area identical to above rectangle is x
∴ Colored part area = → (2)
From above eq (1) and (2), we get
Areas of the colored parts are equal which is equals to
