Question

X-(18-x)+(-9-x) если x= 27

Answer 1

x-(18-x)+(-9-x) если x= 27

Подставляем

27-(18-27)+(-9-27) = 27-(-9)+(-36)= 0

Answer 2

Ответ:

0.

Объяснение:

x - (18 - x) + (-9-x)  = x - 18 + x - 9 - x  = x - 27.

Если х = 27, то

x - 27 = 27 - 27 = 0.

Answer 3

To calculate the expression X-(18-x)+(-9-x) when x = 27, you simply need to substitute the value of x into the expression and perform the arithmetic operations. Here's how you can do it step by step:

1. Replace all instances of "x" with 27: X - (18 - 27) + (-9 - 27)

2. Perform the arithmetic inside the parentheses: X - (-9) + (-36)

3. Simplify the expression further by removing the parentheses: X + 9 - 36

4. Combine like terms: X - 27

Now, since the value of x is given as 27, we can replace X with 27 in the expression:

27 - 27 = 0

So, when x = 27, the expression X-(18-x)+(-9-x) equals 0.
