Answer 2

|-7,3|+|-1,8|-|3,45|=|-9,1|-|3,45|=|-12,55|=12,55 положительное число, потому что модуль.

Answer 3

To evaluate the expression |-7,3|+|-1,8|-|3,45|, we need to calculate the absolute values and perform the operations in the correct order.

|-7,3| = 7,3 (since the absolute value of a positive number is the number itself) |-1,8| = 1,8 (since the absolute value of a negative number is its positive counterpart) |-3,45| = 3,45 (since the absolute value of a negative number is its positive counterpart)

Now let's substitute these values back into the original expression:

7,3 + 1,8 - 3,45

Now we can simplify the expression:

7,3 + 1,8 - 3,45 = 9,1 - 3,45 = 5,65

Therefore, the value of the expression |-7,3|+|-1,8|-|3,45| is 5,65.
