Usando las relaciones entre velocidad, distancia y tiempo, se encuentra que ella condujo a una velocidad media de 90,5 km/h.

--------------------------

La <u>velocidad </u><u>es la distancia dividida por el tiempo</u>, por lo que:

v = \frac{d}{t}

  • Total de 135,75 km, o sea, d = 135,75
  • Llego en 1,5 horas, o sea, t = 1,5

La velocidad es:

v = \frac{d}{t} = \frac{135,75}{1,5}

División de decimales, o sea, seguimos multiplicando los números por 10 hasta que ninguno sea decimal:

v = \frac{135,75}{1,5} = \frac{1357,5}{15} = \frac{13575}{150} = 90,5

Ella condujo a una velocidad media de 90,5 km/h.

4-4x=12+16x will gib brainleist i promise ;)
Delicious77 [7]

Answer:

4-4x=12+16x

−4x+4=16x+12

−4+4−4=16+12−4

-4x=16x+8

-4x-16x=16x+8-16x

-20x=8

-20x/-20 = 8/-20

x= -2/5

A: 2,5
B: 3,1
C: -2,4



Explanation:


When you’re moving right and up you would add however many numbers you moved up to the original points because going right on a graph makes the X a larger number, and going up makes it larger.
