Question

988-c=128×5=?? 1000-a=630:2​

Answer 1

Ответ:

988-с = 128*5

988-с = 640.

с = 988 - 640

с = 348

_______

988 - 348 = 128*5

640 = 640.

1000-а = 630:2

1000-а = 315

а = 1000 - 315.

а = 685

_________

1000-685 = 630:2

315 = 315

Answer 2

988-c=128*5

988-с=640

с=988-640

с=348

1000-a=630:2

1000-а=315

а=1000-315

а=685

Answer 3

First, let's solve the equation 988-c=128×5:

We can start by multiplying 128 by 5: 128 × 5 = 640

Now, we can solve for c by subtracting 640 from 988: 988 - 640 = 348 So, c = 348

Next, let's solve the equation 1000-a=630÷2:

We can start by dividing 630 by 2: 630 ÷ 2 = 315

Now, we can solve for a by subtracting 315 from 1000: 1000 - 315 = 685 So, a = 685

Therefore, the solutions are c = 348 and a = 685.
