Question

|a-b|-|c|=?,a=-3,5;b=-4,5;c=-5 1/2 a)2 b)-1 c)-4,5 d)2/3 e)2,5​

Answer 1

Ответ:с)-4,5

Пошаговое объяснение:

|а-b|-|c|=|-3,5-(-4,5)|-|-5,5|=

=|-3,5+4,5|-|-5,5|=

=|1|-|-5|=( модуль всегда положительный, поэтому снимая модуль всегда получаем число со знаком +)=1-5,5=-4,5

Answer 2

Let's plug in the given values for a, b, and c into the equation and calculate the result step by step:

Given values: a = -3.5 b = -4.5 c = -5.5

|a - b| - |c| = |(-3.5) - (-4.5)| - |-5.5|

First, calculate the absolute difference between a and b: |a - b| = |-3.5 - (-4.5)| = |-3.5 + 4.5| = |1| = 1

Next, calculate the absolute value of c: |c| = |-5.5| = 5.5

Now, substitute the calculated values back into the equation: |a - b| - |c| = 1 - 5.5 = -4.5

So, the value of |a - b| - |c| is -4.5. None of the provided options (a) 2, b) -1, c) -4.5, d) 2/3, e) 2.5) matches this result. It seems there might be an error in the options provided.
