3 0

Answer:

-1.5

Step-by-step explanation:

<u>See steps below:</u>

  • -8x+3=8x+27
  • -8x + 3 - 8x - 3 = 8x+ 27 - 8x - 3          ⇒ add -8x - 3 to both sides in order to collect like terms in the different sides of equation
  • -16x = 24                                               ⇒ simplified
  • x= 24/-16                                               ⇒ divide
  • x= - 1.5                                                   ⇒ answer

Si consideramos que el planeta Tierra tiene forma esférica y un radio de 6 371 km, ¿cuál es el área total del planeta Tierra?
vovikov84 [41]

Respuesta:

5.101 × 10⁸ km²

Explicación:

Primer paso: Información provista

Radio del planeta Tierra (r): 6371 km

Paso 2: Calcular el área del planeta Tierra

Si suponemos que el planeta Tierra tiene forma esférica, podemos calcular su área (A) usando la siguiente fórmula.

A = 4 × π × r²

A = 4 × π × (6371 km)² = 5.101 × 10⁸ km²

#31. I just need to know how you did it! THANK YOU
kirill [66]

Answer:

m=60º

n=30º

Step-by-step explanation:

a triangle is 180º total

an equilateral triangle has all 60º angles

since the one symbol for a right angle is cut between two triangles you can say that the one angle in the equilateral triangle +n=90º

substituting the values 60+n=90

so n=30

Then since a triangle is 180º you can make an equation that says 180=90+m+n

again substituting 180=90+m+30

60=m

an easy way to check is 180=90+30+60             180=180
