Solve the inequality. 5(a – 5) > 25 a < 30 a > 30 a > 5 a > 10

Divide both sides of the inequality by 5 to give an answer of a - 5 > 5. Group all the variables and constants to opposite sides of the inequality. For this given, 
                                  a > 5 + 5
which simplifies into a > 10. Thus, the answer is the fourth choice. 

D.  x = 4.

Step-by-step explanation:

As the 2 angles are congruent:

2.3x +25 = 5.8x + 11

2.3x - 5.8x = 11 - 25

-3.5x = -14

x = 14/3.5

x = 4.
