Question

(1,42 - (- 3,22)):(-0,8)+ (-6)*(-0,7)​

Answer 1

Пошаговое объяснение:

(1,42 - (-3,22)) ÷ (-0,8) + (-6)×(-0,7) = (1,42+3,22) ÷ (-0,8) +4,2= 4,64 ÷ (-0,8) + 4,2= -5,8 + 4,2 = -1,6

Answer 2

To solve the expression (1.42 - (-3.22)) / (-0.8) + (-6) * (-0.7), we can follow the order of operations, which is commonly known as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).

Let's break down the expression step by step:

Step 1: Simplify within parentheses. 1.42 - (-3.22) equals 1.42 + 3.22, which equals 4.64.

After simplifying the expression within the parentheses, the expression becomes: 4.64 / (-0.8) + (-6) * (-0.7)

Step 2: Perform multiplication. (-6) * (-0.7) equals 4.2.

After performing multiplication, the expression becomes: 4.64 / (-0.8) + 4.2

Step 3: Perform division. 4.64 divided by (-0.8) equals -5.8.

After performing division, the expression becomes: -5.8 + 4.2

Step 4: Perform addition. -5.8 + 4.2 equals -1.6.

Therefore, the value of the expression (1.42 - (-3.22)) / (-0.8) + (-6) * (-0.7) is -1.6.
