Answer 1

Ответ:

Пошаговое объяснение:

9+(270-0,34*450):30=12,9

0,34*450=153

270-153=117

117:30=3,9

9+3,9=12,9

Answer 2

Sure, let's break down the expression step by step:

$9 + \left(270 - 0.34 \times 450\right) \div 30$

First, calculate the multiplication inside the parentheses:

$270 - 0.34 \times 450 = 270 - 153$

$= 117$

Next, substitute this value back into the expression:

$9 + 117 \div 30$

Now, perform the division:

$117 \div 30 = 3.9$

Finally, add 9 and 3.9 together:

$9 + 3.9 = 12.9$

So, the value of the expression $9 + \left(270 - 0.34 \times 450\right) \div 30$ is $12.9$.
