Question

1) (- 9,8 + 5,6 – 8,4) : (- 1,4)2) (- 3,6 + 2,7 – 7,2) • 1,8пж решите срочно надо​

Answer 1

Ответ:

1) (-9,8+5,6-8,4):(-1,4)

1.1) -9,8+5,6=-1,54

1.2) Минус и минус будет плюс. Меняем разность на сумму. -1,54+8,4=9,94

1.3) -9,94÷1,4=-7,1

Answer 2

-12.6:(-1.4)= 9

-8.1×1.8= -14.58

Answer 3

Sure, I'd be happy to help you with these calculations!

1. $(-9.8 + 5.6 - 8.4) : (-1.4)$

To solve this, follow the order of operations (PEMDAS/BODMAS):

P: Parentheses first, E: Exponents (none in this case), MD: Multiplication and Division (from left to right), AS: Addition and Subtraction (from left to right).

$= (-2.6) : (-1.4)$ Now, when dividing two negative numbers, it becomes a positive result:

$= 2.6 : 1.4$

Now, divide the two numbers:

$= 1.85714$

So the first expression evaluates to approximately 1.85714.

2. $(-3.6 + 2.7 - 7.2) \cdot 1.8$

Again, follow the order of operations:

$= (-8.1) \cdot 1.8$

Now, multiply the two numbers:

$= -14.58$

So the second expression evaluates to approximately -14.58.

Therefore, the results are:

1. $1.85714$
2. $-14.58$
