Question

(x+y)-z при x-2,1 y-3,7 z- -5

Answer 1

Пошаговое объяснение:

(x+y)-z,  при x = 2,1; y = 3,7; z = -5

(2,1+3,7)-(-5) = 2,1+3,7+5 = 10,8

Answer 2

Ответ:

(2,1+3,7)-(-5)=10,8

Answer 3

To evaluate the expression (x+y)-z with the given values:

x = -2.1 y = 3.7 z = -5

Substituting these values into the expression, we have:

(-2.1 + 3.7) - (-5)

Performing the operations within the parentheses first:

1.6 - (-5)

When subtracting a negative number, it is equivalent to adding the positive number:

1.6 + 5

Finally, performing the addition:

6.6

Therefore, (x+y)-z, when x = -2.1, y = 3.7, and z = -5, is equal to 6.6.
