Answer:

x= 6

Step-by-step explanation:

12+3x=30

3x+12=30

3x+12-12=30-12

3x=30-12

3x=18

3x divided by 3 = 18 divided by 3

x=18 over 3

18 divided by 3 is 6

Answer:

x = 6

Step-by-step explanation:

12 +3x = 30

Subtract 12 from both sides

3x = 30 - 12

3x = 18

Divide both side by 3

x = 18/3

x = 6

Juana compró una camioneta 4x4 a S/ 42 000; además, sabe que la camioneta se depreciará (bajará su precio) en forma lineal duran
prohojiy [21]

Answer:

Una relación lineal es de la forma:

y = a*x + b.

donde a es la pendiente y b es la ordenada al origen.

en este caso, y es el precio de la camioneta, x es el numero de años que pasaron, a es la razon de depreciación de la camioneta y b es el precio inicial de la camioneta, b = $42,000.

Sabemos que después de 5 años, el precio de la camioneta es 21,000, entonces podemos resolver:

$21,000 = a*5 + $42,000

a*5 = $21,000 - $42,000 = -$21,000

a = -$21,000/5 = -$4,200

Esto significa que el precio decae $4,200 por año
