Mathematics

Alina [70]3 years ago
3 0

Answer:

<h2>x = 3</h2>

Step-by-step explanation:

<h3>4x − 5 = −17</h3>

<u>Add 5 to both sides of the equation</u>

That's

<h3>4x + 5 - 5  =  - 17 + 5 \\ 4x =  - 12</h3>

<u>Divide both sides by 4</u>

<h3>\frac{4x}{4}   =   - \frac{12}{4}  \\</h3>

We have the final answer as

<h3>x = 3 \\</h3>

Hope this helps you

La distancia entre la tierra y el sol es de 1,5 . 10˄8 km, la distancia entre la Tierra y Júpiter es de 9,3 . 10˄8 km y Neptuno
Sonbull [250]

A) La distancia del Sol a Neptuno en notación científica es 45 x 10^8 km.  

B) Júpiter se encuentra a 930.000.000 kilómetros del Sol.  

C) La distancia del Sol a Neptuno es 30 veces mayor que la que hay a la Tierra.

Dado que la distancia entre la tierra y el sol es de 1,5 . 10˄8 km, la distancia entre la Tierra y Júpiter es de 9,3 . 10˄8 km y Neptuno está situado a 4.500.000.000 Km del Sol, para determinar:

A) Expresa en notación científica la distancia del sol a Neptuno  

B) Calcula la distancia a la que está situado Júpiter respecto al Sol  

C) Calcula cuantas veces es mayor la distancia del Sol a Neptuno que la que hay a la Tierra.

Deben realizarse los siguientes cálculos:

  • A) 4.500.000.000 = 45 x 100.000.000
  • 100.000.000 = 10^8
  • 4.500.000 = 45 x 10^8

  • B) 9.3 x 10^8 = X
  • 100.000.000 = 10^8
  • 9.3 x 100.000.000 = X
  • 930.000.000 = X

  • C) Tierra = 150.000.000
  • Neptuno = 4.500.000.000
  • 150 = 1
  • 4.500 = X
  • 4500 / 150 = X
  • 30 = X
