Question

Докажите, что выражения 1/2a-0.5(a-44) не зависит от a, соствьте на основе решения тождество

Answer 1

1\2а-0,5*(а-44)=0,5а-0,5а+22=22
То есть   ответе нет буквы а,а значит и не зависит от а

Answer 2

Proving the Expression Independence

To prove that the expression 1/2a - 0.5(a-44) does not depend on the variable 'a', we can simplify the expression and show that it does not contain 'a'.

First, let's simplify the given expression:

1/2a - 0.5(a-44)

We can start by distributing the -0.5 to the terms inside the parentheses:

1/2a - 0.5a + 22

Now, we can combine like terms:

(1/2 - 0.5)a + 22

Simplifying further:

(-0.5)a + 22

As we can see, the expression (-0.5)a + 22 does not contain the variable 'a'. Therefore, it is independent of 'a'.

This proves that the expression 1/2a - 0.5(a-44) does not depend on the variable 'a'.
