Answer 1

Ответ:

а)  3,5*(8,68+1,136)-135,531:33,3=3,5*9,816-4,07=34,356-4,07=30,286

б) (8,94+9,39):(7,57-1,4*2,05)=18,33:(7,57-2,87)=18,33:4,7=3,9

Answer 2

Let's solve these mathematical expressions step by step:

(a) 3.5 * (8.68 + 1.136) - 135.531 / 33.3

First, calculate the expression within the parentheses:

8.68 + 1.136 = 9.816

Now, multiply 3.5 by the result:

3.5 * 9.816 = 34.356

Finally, divide 135.531 by 33.3:

135.531 / 33.3 ≈ 4.066

Now, subtract the result of the division from the previous multiplication:

34.356 - 4.066 ≈ 30.29

So, the answer to (a) is approximately 30.29.

(b) (8.94 + 9.39) / (7.57 - 1.4 * 2.05)

First, calculate the expression within the parentheses:

8.94 + 9.39 = 18.33

Now, calculate the expression within the second set of parentheses:

7.57 - (1.4 * 2.05) = 7.57 - 2.87 = 4.7

Now, divide the result of the first set of parentheses by the result of the second set of parentheses:

18.33 / 4.7 ≈ 3.9

So, the answer to (b) is approximately 3.9.
