Answer 1

Ответ:

Пошаговое объяснение:

580 ÷ 4 + 5 * (509 - 390)

= 145 + 5 * 119

= 145 + 595

= 740

(160 + 36 ÷ 4) + (850 - 181)

= (160 + 9) + 669

= 169 + 669

= 838

36 ÷ 4 + (621 - 96) - 16 * 5

= 9 + (525) - 80

= 9 + 525 - 80

= 454

21 * 3 * 9 - (287 + 114) - 226

= 567 - (401) - 226

= 567 - 401 - 226

= -60

719 - (432 - 16) ÷ 4 - (20 - 16)

= 719 - (416 ÷ 4) - 4

= 719 - 104 - 4

= 611 - 4

= 607

33 * (821 - 810) + (349 + 589)

= 33 * 11 + 938

= 363 + 938

= 1301

Отже, отримані значення виразів:

10. 740

838

Answer 2

Let's solve each of these mathematical expressions step by step:

10. $580: 4 + 5 \cdot (509 - 390) =$

First, solve the expression inside the parentheses:

$509 - 390 = 119$

Now, multiply 5 by 119:

$5 \cdot 119 = 595$

Finally, divide 580 by 4 and add the result to 595:

$580: 4 + 595 = 145 + 595 = 740$

So, the answer is 740.

11. $(160 + 36: 4) + (850 - 181) =$

First, perform the division inside the parentheses:

$36: 4 = 9$

Now, add 160 and 9:

$160 + 9 = 169$

Next, subtract 181 from 850:

$850 - 181 = 669$

Finally, add 169 to 669:

$169 + 669 = 838$

So, the answer is 838.

12. $36: 4 + (621 - 96) - 16 \cdot 5 =$

First, perform the division:

$36: 4 = 9$

Next, subtract 96 from 621:

$621 - 96 = 525$

Now, multiply 16 by 5:

$16 \cdot 5 = 80$

Finally, subtract 80 from the sum of 9 and 525:

$9 + 525 - 80 = 454$

So, the answer is 454.

13. $21 \cdot 3 \cdot 9 - (287 + 114) - 226 =$

First, calculate the product of 21, 3, and 9:

$21 \cdot 3 \cdot 9 = 567$

Now, add 287 and 114:

$287 + 114 = 401$

Finally, subtract 401 and 226 from 567:

$567 - 401 - 226 = -60$

So, the answer is -60.

14. $719 - (432 - 16): 4 - (20 - 16) =$

First, subtract 16 from 432:

$432 - 16 = 416$

Now, perform the division:

$416: 4 = 104$

Next, subtract 16 from 20:

$20 - 16 = 4$

Finally, subtract 104 from 719 and then subtract 4:

$719 - 104 - 4 = 611$

So, the answer is 611.

15. $33 \cdot (821 - 810) + (349 + 589) =$

First, calculate the difference between 821 and 810:

$821 - 810 = 11$

Now, multiply 33 by 11:

$33 \cdot 11 = 363$

Next, add 349 and 589:

$349 + 589 = 938$

Finally, add 363 and 938:

$363 + 938 = 1301$

So, the answer is 1301.
