Question

2,1*(-3,2)-2,1*0,8/0,3:0,5*(-2)

Answer 1

Ответ:

В решении.

Пошаговое объяснение:

(2,1 * (-3,2) - 2,1 * 0,8) /(0,3 : 0,5 * (-2)) =

= (2,1 * ( -3,2 - 0,8)) / (-1,2) =

= (2,1 * (-4)) / (-1,2) =

=( -8,4) / (-1,2) = 7.

Answer 2

To simplify the expression, you should follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders (i.e., powers and square roots, etc.), Multiplication and Division (left-to-right), and Addition and Subtraction (left-to-right).

Let's break down your expression step by step:

1. Start with the multiplication and division within parentheses: 2.1 * (-3.2) - 2.1 * 0.8 / 0.3 : 0.5 * (-2)

2. Calculate the products within the parentheses: -6.72 - 1.68 / 0.3 : -1.0

3. Next, perform the division within the expression: -6.72 - 5.6 : -1.0

4. Finally, do the subtraction: -6.72 - (-5.6)

To subtract a negative number, you can think of it as adding the positive number: -6.72 + 5.6

Now, perform the addition: -1.12

So, the simplified result of the expression is -1.12.
