Answer 1

Ответ:-11.1

Объяснение:

Answer 2

Превратим десятичные дроби в смешанные, а после в неправильные:

$(-6\frac{5}{10} + \frac{1}{3}) * 1\frac{8}{10} = -11,1$

1) $-\frac{65}{10} + \frac{1}{3} = -\frac{195}{30} + \frac{10}{30} = -\frac{185}{30} = -\frac{37}{6}$

2) $-\frac{37}{6} * \frac{18}{10} = -\frac{111}{10} = -11,1$

Ответ: -11,1. Вариант ответа Г)

Answer 3

To solve this expression, we need to follow the order of operations, which is PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

In this case, we only have multiplication and subtraction, so we can perform them in any order. Let's start by simplifying the expression inside the parentheses:

(-6.5 + 1/3) = (-19/3 + 1/3) = -18/3 = -6

Now we can substitute this value back into the original expression and simplify:

(-6 * 1.8) = -10.8

So the answer is -10.8.
