Question

ayudenme porfavoooorrrrr y te doy 17

Answer 1

Explicación paso a paso:

1.

12 - x = 6 - 4

12 - x = 2

12 - 2 = x

10 = x

x - 3 = 4 - 2

x - 3 = 2

x = 2 + 3

x = 5

2.

$\frac{6}{x} = \frac{4}{12} \\\frac{6}{x} = \frac{4}{4.3} \\\frac{6}{x} = \frac{1}{3}\\6(3) = x\\18 = x$                    $\frac{x}{3} = \frac{4}{2} \\\frac{x}{3} = 2\\x = 2(3)\\x = 6$

3.

a - b = c -(cuarta diferencial)

9 - 7 = 5 - x

2 = 5 - x

x = 5 - 2

x = 3

20 - 17 = 15 -  x

3 = 15 - x

x = 15 - 3

x = 12

4.

a - b = b - (tercera diferencial)

12 - 10 = 10 - x

2 = 10 - x

x = 10 - 2

x = 8
