382×905+618×950 по действиям пж 749×709+251×709 1027×378-72÷36×905-628÷4 (650×15+350×15)×0+800÷32-25

Answer 1

А) 1027х378-72:36х905-628:4 = 386 239
1) 1027х378 = 388 206
2) 72:36 = 2
3) 2х905= 1810
4) 628:4=157
5) 388 206 - 1810 = 386 396
6) 386 396 - 157 = 386 239
б) (650х15+350х15)х0+800:32-25 = 
1) 650х15= 9 750 
2) 350х15 = 5 250
3) 9 750 + 5 250 = 15 000 
4) 15 000х0 = 0
5) 800:32 = 25
6) 0 + 25 = 25
7) 25 - 25 = 0
в) 382х905 + 618х950 = 950 х ( 382 + 618 ) = 950 х 1000 = 950 000
г) 749х709 + 251х709 = 709 х ( 749 + 251 ) = 709 х 1000 = 7 090 000

Answer 2

Let's break down the given expressions step by step:

1. 382×905 + 618×950: Multiply the values separately and then add the results: 382 × 905 = 345,910 618 × 950 = 587,100 345,910 + 587,100 = 933,010

   Therefore, 382×905 + 618×950 equals 933,010.

2. 749×709 + 251×709: Similar to the previous expression, we multiply and then add: 749 × 709 = 530,641 251 × 709 = 178,159 530,641 + 178,159 = 708,800

   Thus, 749×709 + 251×709 equals 708,800.

3. 1027×378 - 72÷36×905 - 628÷4: Let's simplify this expression step by step:

   First, perform the divisions: 72 ÷ 36 = 2 628 ÷ 4 = 157

   Now, substitute the values back into the expression: 1027 × 378 - 2 × 905 - 157

   Perform the multiplications: 1027 × 378 = 388,506 2 × 905 = 1,810 157

   Substitute the values back into the expression: 388,506 - 1,810 - 157

   Perform the subtractions: 388,506 - 1,810 - 157 = 386,539

   Hence, 1027×378 - 72÷36×905 - 628÷4 equals 386,539.

4. (650×15 + 350×15)×0 + 800÷32 - 25: Let's evaluate this expression step by step:

   First, perform the additions: 650 × 15 = 9,750 350 × 15 = 5,250 9,750 + 5,250 = 15,000

   Substitute the value back into the expression: (15,000) × 0 + 800 ÷ 32 - 25

   Perform the divisions: 800 ÷ 32 = 25

   Substitute the value back into the expression: (15,000) × 0 + 25 - 25

   Perform the subtractions: 25 - 25 = 0

   Therefore, (650×15 + 350×15)×0 + 800÷32 - 25 equals 0.

I have computed the values for the given expressions based on the given operations.
