Answer:

La respuesta a tu pregunta es:  El granjero tiene 221 gallinas y 109 cerdos

Step-by-step explanation:

Datos

Animales totales = 330 entre gallinas y cerdos

numero total de patas = 878 patas

# de gallinas = ?

# de cerdos = ?

Gallinas = g

Cerdos = c

Sabemos que las gallinas tienen 2 patas y los cerdos tienen 4 patas

Ecuaciones

                              g + c = 330     (I)

                           2g + 4 c = 878   (II)

Resolver las ecuaciones por eliminación

Multiplicar I por -4

                           -4g - 4c = -1320

                            2g + 4c =   878

                           -2g        = -442

                              g = -442/ -2

                              g = 221

Sustituir g en I

                        221 + c = 330

                        c = 330 - 221

                       c = 109

<3 = 180 - <1

<3 = 180 - 90

<3 = 90°

14.

<8 = 180 - <6

<8 = 180 - 137

<8 = 43°

15.

<4 = 180 - <2

<4 = 180 - 34

Mia is helping her glee club raise money to fund a field trip. The glee club secided to sell pencils, which come in boxes of 100
Nitella [24]

Answer:

m = 2500b

Step-by-step explanation:

As instructed,

let b = number of boxes sold

let m = total money made.

The total money made, is a function of the number of boxes sold.

Let me break this down:

There are 100 pencils in a box;

if they sold only one box, they will get 100 X $25 = $2500;

if they sold two boxes, they will get 200 X $25 = $5000;

if they sold three boxes, they will get 300 X $25 = $7500;

Following the trend, we can deduce that money made, m = (number of boxes sold X 100 ) X $25

representing this using the variables we were given, we have

m = 100b X 25

hence

m = 2500b
