Question

Doy CORAZÓN Y 5 ESTRELLAS Y CORONA AL QUE RESPONDA ESTO​

Answer 1

Respuesta:

1) 30

2) 100

3) 20

4) 343

5) 34

6) 64

7) 63

Explicación paso a paso:

$\frac{x}{6} + 7 = 12$

$\frac{x}{6} = 5$

x = 30

8n + 50 = 850

8n = 800

n = 100

6a - 11 = 109

6a = 120

a = 20

$\frac{x}{7} = 49$

x = 49 . 7

x = 343

2y + 12 = 80

2y = 68

y = 34

4n - 6 = 250

4n = 256

n = 64

2x - 100 = 26

2x = 126

x = 63

Answer 2

Explicación:

1. x/6 + 7 = 12 -> x/6=5 -> x= 30.
2. 8n + 50 = 850 -> 8n = 800 -> n = 100.
3. 6a - 11 = 109 -> 6a = 98 -> a= 98/6.
4. x/7 = 49 -> x = 343.
5. 2y + 12 = 80 -> 2y = 68 -> y= 34.
6. 4n - 6 = 250 -> 4n= 256 -> n = 64.
7. 2x - 100 = 26 -> 2x= 126 -> x = 63.
