Answer:

El estudiante obtuvo una calificación de 3.5 en su última evaluación.

Step-by-step explanation:

Dado que un estudiante obtuvo calificaciones de 5,7, 6,2 y 4,6 obteniendo un promedio total de 5 en sus calificaciones, para determinar qué nota obtuvo en la ultima prueba para lograr ese promedio, se debe realizar el siguiente cálculo:

(5.7 + 6.2 + 4.6 + X) / 4 = 5

(16.5 + X) / 4 = 5

16.5 + X = 4 x 5

16.5 + X = 20

X = 20 - 16.5

X = 3.5

which ordered pairs in the form (x, y) are solutions to the equation 3x−4y=21 ? Select each correct answer. (−1, −6) (−3, 3) (11
Valentin [98]

Answer:

see explanation

Step-by-step explanation:

To determine which ordered pairs are solutions to the equation

Substitute the x and y values into the left side of the equation and if equal to the right side then they are a solution.

(- 1, - 6)

3(- 1) - 4(- 6) = - 3 + 24 = 21 = right side ← thus a solution

(- 3, 3)

3(- 3) - 4(3) = - 9 - 12 = - 21 ≠ 21 ← not a solution

(11, 3)

3(11) - 4(3) = 33 - 12 = 21 = right side ← thus a solution

(7, 0)

3(7) - 4(0) = 21 - 0 = 21 = right side ← thus a solution

The ordered pairs (- 1, - 6), (11, 3), (7, 0) are solutions to the equation
