Answer 1

Ответ:

9.65

Объяснение:

(-2,8) : 7 + (-4,02): (-0,4​) = 9.65

1) (-2,8) : 7 = -0.4

2) (-4,02) : (-0,4​) = 10.05

3) -0.4 + 10.05 = 9.65

Answer 2

To calculate the result of the expression $(-2,8) : 7 + (-4,02) : (-0,4)$, we'll break it down step by step following the order of operations (PEMDAS - Parentheses, Exponents, Multiplication and Division, Addition and Subtraction):

1. Evaluate $(-2,8) : 7$:

   $$(-2,8) \div 7 = -0.4 \text{ (approximately)}$$

2. Evaluate $(-4,02) : (-0,4)$:

   $$(-4,02) \div (-0,4) = 10.05 \text{ (approximately)}$$

3. Add the results from steps 1 and 2:

   $$-0.4 + 10.05 = 9.65 \text{ (approximately)}$$

So, $(-2,8) : 7 + (-4,02) : (-0,4) \approx 9.65$.
