two times a number added to another number is 20. three times the first number minus the other number is 20. find the numbers
skelet666 [1.2K]

Answer:

y=7

Step-by-step explanation:

We have two numbers,  

x

,

y

. We know two things about them:

2

x

+

y

=

25

3

x

−

y

=

20

Let's add these two equations together which will cancel the  

y

:

5

x

+

0

y

=

45

x

=

45

5

=

9

We can now substitute in the  

x

value into one of the original equations (I'll do both) to get to  

y

:

2

x

+

y

=

25

2

(

9

)

+

y

=

25

18

+

y

=

25

y

=

7

3

x

−

y

=

20

3

(

9

)

−

y

=

20

27

−

y

=

20

en una encuesta a 200niños sobre el programa de T.V. que más les gusta ver ,se encontró que a 30 niños ven dibujos animados 45 n
Lelu [443]

Answer:

15% de los niños solo ven dibujos animados, 22.5% solo ven películas animadas, 27.5% ven programas sobre animales, 19% miran programas sobre animales y dibujos animados, y 16% ve los tres tipos de programas.

Step-by-step explanation:

Dado que en una encuesta a 200 niños sobre el programa de TV que más les gusta ver se encontró que 30 niños ven dibujos animados, 45 niños miran películas animadas, 55 niños miran programas sobre animales, 38 niños miran programas sobre animales y dibujos animados y 32 niños miran los tres tipos de programas, para determinar el porcentaje de cada grupo​ se deben realizar los siguientes cálculos:

30/200 = 15/100 = 15%

45/200 = 22.5/100 = 22.5%

55/200 = 27.5/100 = 27.5%

38/200 = 19/100 = 19%

32/200 = 16/100 = 16%

Así, 15% de los niños solo ven dibujos animados, 22.5% solo ven películas animadas, 27.5% ven programas sobre animales, 19% miran programas sobre animales y dibujos animados, y 16% ve los tres tipos de programas.
