Answer 2

Ответ:

Пошаговое объяснение:

3,6 * 0,5 - 8,2 * (-1,5) = 1,8 + 12,3 = 14,1

Answer 3

To evaluate the expression 3.6x - 8.2y when x = 0.5 and y = -1.5, we substitute the given values into the expression:

3.6(0.5) - 8.2(-1.5)

First, we calculate the value inside the parentheses:

3.6(0.5) = 1.8

Similarly, we calculate the value inside the second set of parentheses:

8.2(-1.5) = -12.3

Now, we substitute the calculated values back into the expression:

1.8 - (-12.3)

To subtract a negative number, we can rewrite it as addition:

1.8 + 12.3

Adding these values gives us:

14.1

Therefore, when x = 0.5 and y = -1.5, the value of 3.6x - 8.2y is 14.1.
