Durante sus vacaciones y con la finalidad de informarse sobre las nuevas tendencias pedagogicas 90 docentes se inscribieron para participar en una jornada pedagogica. se sabe que asistieron el 70% de los profesores inscritos y el 30% de las profesoras inscritas, lo que hizo un total de 47 docentes.¿cuantos profesores asistieron? ¿y cuantas profesoras?

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.

the radius is 2 times the diameter.

step-by-step explanation:

it's d

step-by-step explanation:

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.
