This is an addition problem. Let's start with ith oz. 4 oz plus 14 oz = 18 oz. Now, put 18 oz aside. So, we have to add 8 lbs plus 14 lbs = 22 lbs. Now, you have to put it together - 22 lbs 18 oz (because lbs comes before oz)

I hope this helps! Have a good day! -Wajiha

Just add the weights together.  This comes out to 22lb and 18 oz, but there are 16 oz in a pound, so 23 lb and 2 oz.

Old McDonald has some chickens and some cows. He counted 56 heads and 116 legs. How many chickens and how many cows does old McD
Elza [17]

Answer: old McDonald has 54 chickens and 2 cows.

Step-by-step explanation:

Let x represent the number of chickens that old McDonald have.

Let y represent the number of cows that old McDonald have.

He counted 56 heads. A chicken and a cow has one head each. It means that

x + y = 56

He counted 116 legs. A chicken has 2 legs and a cow has 4 legs. It means that

2x + 4y = 116 - - - - - - - - -1

Substituting x = 56 - y into equation 1, it becomes

2(56 - y) + 4y = 116

112 - 2y + 4y = 116

- 2y + 4y = 116 - 112

2y = 4

y = 4/2 = 2

x = 56 - y = 56 - 2

x = 54

What is an equation of the line that passes through the points <br> (8,2) and <br> (7,1)?
gogolik [260]

Answer:

Step-by-step explanation:

first, we find the slope

slope = (y2 - y1) / (x2 - x1)

(8,2)....x1 = 8 and y1 = 2

(7,1)....x2 = 7 and y2 = 1

now we sub

slope = (1 - 2) / (7 - 8) = -1/-1 = 1

y = mx + b

slope(m) = 1

use either of ur points...I will use (8,2)...x = 8 and y = 2

now we sub and find b, the y intercept

2 = 1(8) + b

2 = 8 + b

2 - 8 = b

-6 = b

so ur equation is : y = 1x - 6....or just y = x - 6 <===

Por qué crees que el valor de la media no aparece en la tabla y es un número decimal?
vovikov84 [41]

La media no aparece en la tabla ya que se requiere un calculo para encontrarla, además, es un número decimal pues corresponde a la suma de los resultados dividida en el número de días.

<h3>¿Qué es la media?</h3>

En matemáticas, la media o promedio corresponde a la suma de todos los valores dividida en el número total de valores. En este caso la media corresponde a la suma de las temperaturas dividida en el número de días.

Calcular la media:

Usando la formula anterior, calculemos la media:

  • 16 + 19 +17 + 20 + 22 + 18 +15 = 127/7 = 18.7

El valor de la media es 18.7, al respecto se puede observar que:

  • Este valor no aparee en la tabla pues no corresponde a la temperatura de ningún día sino que debe ser calculado.
  • Este valor es decimal, lo que se común al hallar la media ya que se suman todos los valores y se dividen por un número determinado.

Nota: Esta pregunta esta incompleta. Aquí esta la parte faltante:
