Answer:
original number = 53
Step-by-step explanation:
In two digits number:
Let the tens place digit be x and units place digit be y.
So,
Original number = 10x + y
Number obtained after reversing the digits = 10y + x
According to the first condition:
x + y = 8.... (1)
According to the second condition:
10y + x = 10x + y - 18
10y + x - 10x - y = - 18
9y - 9x = - 18
-9(x - y) = - 18
x - y = - 18/(-9)
x - y = 2.......(2)
Adding equations (1) & (2), we find
x + y + x - y = 8 + 2
2x = 10
x = 10/2
x = 5
Plug x = 5 in equation (1), we find:
5 + y = 8
y = 8 - 5
y = 3
10x + y = 10*5 +3 = 50 + 3 = 53
Hence, original number = 53
Answer:
Is there a picture of the table I will try and solve but I'm not sure if I can
A is the answer to your question
Answer:
x > 0
Step-by-step explanation:
Division by zero is not defined. Therefore, x must be greater than zero. Also: The square root function is defined only for x greater than zero or equal to zero. Together these restrictions tell us that the domain is (0, infinity ).
