Answer:

n = 3.6

Step-by-step explanation:

Start by removing the brackets on both sides.

28 - 14n = -2n -2n - 8

Combine like terms on the right.

28 - 14n = - 4n - 8  

Add 14n to both sides.

28 -14n + 14n = -4n + 14n -8

Combine like terms

28 = 10n - 8  

Add 8 to both sides

28 + 8 = 10n - 8 + 8

Combine like terms

36 = 10n

Divide by 10

36/10 = 10n/10

n = 3.6

n=3.6

Do the distributive property to both sides then add 14n to -4n and get 10n then add 8 to both sides to get 36, the u have 10n=36 then divide each side by 10, 10/10 cancel each other then 36/10 = 3.6 so N=3.6

Of the 20 people in the store, 6 are from out-of-state. What percent of the people are from out-of-state?
MAXImum [283]

Step-by-step explanation:

Let’s set up a proportion.

6/20=x\100 (percent is always out of 100. set parts and wholes equal)

x=30

30 percent of the people are from out of state.

Answer:

a) 1 : 100

1 cm en el mapa equivalen a 100 cm en la realidad

b) 1 : 1000

1 cm en el mapa equivalen a 1000 cm en la realidad

c) 1 : 2000

1 cm en el mapa equivalen a 2000 cm en la realidad

d) 1 : 18000

1 cm en el mapa equivalen a 18000 cm en la realidad

Step-by-step explanation:

Tenemos 4 escalas :

a) 1 : 100

b) 1 : 1000

c) 1 : 2000

d) 1 : 18000

Definimos ''escala'' como una relación entre dos números ''a'' y ''b'', generalmente ''a'' y ''b'' son números naturales. Denotamos la escala como :

a : b

En dónde ''a'' representa la longitud del dibujo y ''b'' la longitud real.

Por ende, cuando a estamos en presencia de una escala de reducción y cuando a>b estamos en presencia de una escala de ampliación.

La escala a=b ó 1 : 1 se define como escala natural.

Analicemos cada caso :

a) 1 : 100

Aquí vemos que es una escala de reducción (dado que 1 < 100) por ende cualquier magnitud de longitud en el mapa será 100 veces más grande en la vida real.

En este caso, 1 cm en el mapa equivalen a 100 cm en la realidad.

Análogamente y con el mismo razonamiento, escribimos las relaciones para los casos b), c) y d)  

b) 1 cm en el mapa equivalen a 1000 cm en la vida real

c) 1 cm en el mapa equivalen a 2000 cm en la vida real

d) 1 cm en el mapa equivalen a 18000 cm en la vida real

b), c) y d) también representan escalas de reducción.
