Doña carmelita esta enferma. el doctor le receto 3 pastillas diferentes: la primera deberá tomarla cada 2 horas, la segunda cada 8 horas y la tercera cada 5 horas .
si el tratamiento lo inicio a las 8 de la mañana tomándose juntas las 3 pastillas
¿a qué hora volverán a coincidir las pastillas?

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.
