Question

24а + 47а + 53а + 76а Если а=47 128р - 72р - 28р Если р=11 14х + 27х = 656 81у - 38у = 645 49z - z = 384 102k - 4k = 1960

Answer 1

Ответ:

24а + 47а + 53а + 76а= 9400

128р - 72р - 28р= 308

14х + 27х = 656

x=16

81у - 38у = 645

y=15

49z - z = 384

z=8

102k - 4k = 1960

k=20

Пошаговое объяснение:

14х + 27х = 656

41x=656

x=656\41

x=16

81у - 38у = 645

43y=645

y=645/43

y=15

49z - z = 384

48z=384

z=384/48

z=8

102k - 4k = 1960

98k=1960

k=1960/98

k=20

Answer 2

Ответ:

1-9400, 2-308, 3-16, 4-15, 5-8, 6-20.

Пошаговое объяснение:

1) 24a + 47a + 53a + 76a = 200a = 200×47 = 9400, если a=47

2) 128p - 72p - 28p = 28p = 28×11 = 308, кслт р = 11

3) 14x + 27x = 656

41x = 656

x = 656/41

x= 16

4) 81y - 38y = 645

43y = 645

y = 645/43

y = 15

5) 49z - z = 384

48z = 384

z = 384/48

z = 8

6) 102k - 4k = 1960

98k = 1960

k = 1960/98

k =  20

Answer 3

To solve these expressions, simply substitute the given values for the variables and perform the calculations. Let's solve each expression step by step:

1. 24а + 47а + 53а + 76а, where а = 47 Replace а with 47: 24 * 47 + 47 * 47 + 53 * 47 + 76 * 47 Now calculate the result: 1128 + 2209 + 2491 + 3572 = 9400

2. 128р - 72р - 28р, where р = 11 Replace р with 11: 128 * 11 - 72 * 11 - 28 * 11 Now calculate the result: 1408 - 792 - 308 = 308

3. 14х + 27х = 656 Combine like terms: 14x + 27x = 656 41x = 656 Solve for x: x = 656 / 41 x = 16

4. 81у - 38у = 645 Combine like terms: 81y - 38y = 645 43y = 645 Solve for y: y = 645 / 43 y = 15

5. 49z - z = 384 Combine like terms: 49z - z = 384 48z = 384 Solve for z: z = 384 / 48 z = 8

6. 102k - 4k = 1960 Combine like terms: 102k - 4k = 1960 98k = 1960 Solve for k: k = 1960 / 98 k = 20

So, the solutions for each expression are:

1. 24а + 47а + 53а + 76а, where а = 47: 9400
2. 128р - 72р - 28р, where р = 11: 308
3. 14х + 27х = 656: x = 16
4. 81у - 38у = 645: y = 15
5. 49z - z = 384: z = 8
6. 102k - 4k = 1960: k = 20
