The two numbers are 4.95 and 2.25.
<h3>
Explanation: </h3>
Let the two numbers be x and y. Given conditions,
...............................(1)
................................(2)
Adding equations (1) and (2), we get
![LHS = x+y+x-y = (2x - y+y) = 2x\\RHS=7.2+2.7 = 9.9](https://tex.z-dn.net/?f=LHS%20%3D%20x%2By%2Bx-y%20%3D%20%282x%20-%20y%2By%29%20%3D%202x%5C%5CRHS%3D7.2%2B2.7%20%3D%209.9)
Therefore ![2x = 9.9; x=9.9/2 = 4.95](https://tex.z-dn.net/?f=2x%20%3D%209.9%3B%20x%3D9.9%2F2%20%3D%204.95)
x=4.95 .......................(3)
Substituting value of x from (3) in (1), we get
![x+y = 7.2\\4.95+y=7.2\\y=7.2-4.95 = 2.25](https://tex.z-dn.net/?f=x%2By%20%3D%207.2%5C%5C4.95%2By%3D7.2%5C%5Cy%3D7.2-4.95%20%3D%202.25)
y=2.25 ........................(4)
From (3) and (4), the two numbers are 4.95 and 2.25.
Ordered pair.. ordered pair as this a pair to make one coordinate
Answer:
12a + 24 = 6(2a + 4)
Step-by-step explanation:
Given the numbers :
4, 12a 6 2a and 24 ; create an equivalent expression :
12a, 2a, 4, 6, 24
We could separate tbe constant terms and those with variables :
12a, 2a ; 6, 4, 24
We could put the larger digit to one side
12a + 24 = 6(2a + 4)
This way the Right hand side is equal to the left hand side.
Check:
12a + 24 = 6(2a + 4)
12a + 24 = 12a + 24
Hence, the proof
Angle EBD and Angle DBE are adjacent
