Answer:

see explanation

Step-by-step explanation:

Given that the first term is - 10 and the common difference between consecutive terms is - 2, then

To obtain the next term from the previous term subtract 2 from it

- 10 - 2 = - 12, - 12 - 2 = - 14, - 14 - 2 = - 16, - 16 - 2 = - 18 and so on

The first 10 terms are

- 10, - 12, - 14, - 16, - 18, - 20, - 22, - 24, - 26, - 28

18 cajas de manzanas y peras fueron llevadas a la escuela. Las peras trajeron 210 kg en 6 cajas. ¿Cuántos kilos de manzanas fuer
Katyanochek1 [597]

Answer:

504 kilos de manzanas fueron llevados a la escuela.

Step-by-step explanation:

Sean x, y la cantidad de cajas de manzanas y peras, respectivamente. De acuerdo con el enunciado, tenemos el siguiente sistema de ecuaciones:

Total de cajas

x+y = 18 (1)

Masa de cada caja de peras

y\cdot m_{P} = 210 (2)

y = 6 (3)

Masa de caja de manzanas

m_{M} = m_{P}+7 (4)

De (2) en (3), tenemos que la masa de cada caja de peras es:

m_{P} = 35\,kg

Por (4), encontramos que la masa de cada caja de manzanas es:

m_{M} = 35\,kg+7\,kg

m_{M} = 42\,kg

Finalmente, de (1) tenemos la cantidad de cajas de manzana:

x = 18-y

x = 12

La cantidad de kilos de manzanas llevada a la escuela se obtiene al multiplicar la cantidad de cajas de manzana por la masa de cada caja:

M = (12)\cdot (42\,kg)

M = 504\,kg

504 kilos de manzanas fueron llevados a la escuela.

A number r is more than 0 or less than or equal to ‐8
Butoxors [25]

Answer

-8 \geq r > 0

Step-by-step explanation:

you know that r is less than or equal to -8, so you write that, and then you know that r is also greater than 0, so then you add that to it, and then you have the answer. r will be in the middle because it is the range of what are can be.

Write an equation that represents the line that passes through the points (5,4) and (-5,0)
Assoli18 [71]
Slope = (0 - 4)/(-5-5) = -4/-10 = 2/5 

y = mx + b
4 = (2/5) (5)  + b
4 = 2 +b
b = 2

equation

y = 2/5x + 2
