Question

(5,3-2,85) * (2,4 – 1,14) + (10 – 1,4) * (14,1 – 11,6);​

Answer 1

Ответ:

А ) ( 5,3 - 2,85) * (2,4-1,14)+ (10-1,4)* (14,1-11,6) = 2,45*1,26 + 8,6 * 2,5 = 3,087 + 21,5 = 24,587

б) (532,4-198,7)*(24-1,8)+2,634*(15-12,5)=333,7*22,2+2,634*2,5= 7408,14+6,585=7414,725

В) (1,6 + 0,89+0,01) * (13,4+0,77+7,96) + (19-14,5)=2,5 * 22,13 + 4,5 = 55,325+4,5=59,825

Пошаговое объяснение:

5,3 - 2,85) * (2,4-1,14)+ (10-1,4)* (14,1-11,6) = 2,45*1,26 + 8,6 * 2,5 = 3,087 + 21,5 = 24,587

Answer 3

To calculate the expression (5.3 - 2.85) * (2.4 - 1.14) + (10 - 1.4) * (14.1 - 11.6), you can follow these steps:

Step 1: Calculate the values inside the parentheses:

• Inside the first set of parentheses: 5.3 - 2.85 = 2.45

• Inside the second set of parentheses: 2.4 - 1.14 = 1.26

• Inside the third set of parentheses: 10 - 1.4 = 8.6

• Inside the fourth set of parentheses: 14.1 - 11.6 = 2.5

Step 2: Perform the multiplications and additions:

Now, plug these values back into the original expression:

(2.45) * (1.26) + (8.6) * (2.5)

Step 3: Calculate the products:

2.45 * 1.26 = 3.087

8.6 * 2.5 = 21.5

Step 4: Add the products:

3.087 + 21.5 = 24.587

So, the result of the expression (5.3 - 2.85) * (2.4 - 1.14) + (10 - 1.4) * (14.1 - 11.6) is approximately 24.587.
