inn [45]

Happy Valentines Day!

Answer:

d = 2t

Step-by-step explanation:

The reason I say this is because it says d first followed by an equal sign which is d = and it says in the problem that he walks 2 kilometers every trip to school so it should 2t because it is 2 kilometers for one trip times how many trips he takes.

Hope This Helps :)

Una empresa fabrica dos modelos de DVD: el modelo A y el modelo B. Se dispone de 50 kilogramos de caucho y de 80 horas de mano d
alexandr1967 [171]

Answer:

¿Cuántos DVD de cada tipo debe fabricar y vender para que la utilidad sea máxima?

Se debe fabricar y vender 20 DVD del modelo A y 30 DVD del modelo B. La utilidad máxima es de de S/. 1 800

Step-by-step explanation:

x : Número de DVD del modelo A

y : Número de DVD del modelo B.

                               MODELO A MODELO B TOTAL

Cantidad de caucho                  1x 1x                 50 kg.

Horas de mano de obra           1x 2x                 80 horas

U : Utilidad mensual.

La función objetivo, que se debe maximizar, es:

U=30   + 40y

x+ y \leq 50\\  

x + 2y \leq 80

x\geq 0

y\geq 0

Las coordenadas de los vértices de la región factibles son:

A (0, 0) B (50, 0) C (20, 30) D(0, 40)

Entonces, se evalúa la función objetivo en cada punto:

U (0, 0) = 30 (0) + 40 (0) = 0

U (50, 0) = 30 (50) + 40(0) = 1500

U (90, 0) = 30 (20) + 40 (30) = 1800

U (0, 40) = 30 (0) + 40 (40) =1600

Por consiguiente U tiene un valor máximo en C , en donde: x =20 ,  y = 30 .

Se debe fabricar y vender 20 DVD del modelo A y 30 DVD del modelo B. La utilidad máxima es de de S/. 1 800.

 

 30 x  40 y

Use inverse operations to solve X - 5.6 = -1.7
DedPeter [7]
The inverse operation of subtraction is addition. Lets use the inverse operation to solve x. Lets do it:-

x - 5.6 = -1.7
-1.7 + 5.6 = x
-1.7 + 5.6 = 3.9 
x = 3.9

CHECK OUR WORK:-

3.9 - 5.6 = -1.7
We were RIGHT!!

So, x = 3.9.

Hope I helped ya!!
