8x+ 18 + 3x-3 = 180  straight line

combine like terms

11x+15 = 180

subtract 15 from each side

11x = 165

divide by 11

x = 15

<rsu = 8x+18

      = 8*15+18 = 138

< ust = 3x-3

    = 3*15-3 = 42

Si a la tercera parte de un número le sumas tres, obtienes el mismo resultado que si al número lo divides entre dos y le restas
nataly862011 [7]

Answer:

24

Step-by-step explanation

La información presentada indica que a la tercera parte de un número le sumas tres esto significa que un número x lo divides entre 3 y le sumas tres. Después dice que esto será igual que si al número lo divides entre dos y le restas uno, lo que puedes escribir como (x/2)-1. De acuerdo a esto puedes plantear una igualdad:

\frac{x}{3}+3=\frac{x}{2}-1

Después, puedes despejar x para encontrar su valor. Primero pasas x/2 a restar a la izquierda de la igualdad y pasas el 3 a restar a la derecha.

\frac{x}{3}-\frac{x}{2}=-1-3

Luego, resuelves las restas a cada lado:

\frac{2x-3x}{6}=-4

-\frac{1}{6}x=-4

Ahora despejas x pasando -1/6 que está multiplicando al lado derecho de la siguiente forma:

x=-4*(-\frac{6}{1})

x=24

De acuerdo a esto, la respuesta es que el número es 24.

24/3+3= 8+3= 11

24/2-1= 12-1= 11

Two hikers are miles apart and walking toward each other. They meet in hours. Find the rate of each hiker if one hiker walks mph
lorasvet [3.4K]

Complete question : Two hikers are 33 miles apart and walking toward each other. They meet in 5 hours. Find the rate of each hiker if one hiker walks 2.2 mph faster than the other. The speed of the slow hiker is nothing ​mph, and the speed of the fast hiker is nothing mph.

Answer:

2.2 mph ; 4.4 mph

Step-by-step explanation:

Given that :

Total distance apart = 33

Time taken = 5 hours

Rate of slow hiker = x

Rate of fast hiker = x + 2.2

Speed (rate) = distance / time

Distance = speed * time

Distance covered by fast hiker + distance covers by slow hiker

(x + 2.2)*5 + 5x = 33

5x + 11 + 5x = 33

10x = 33 - 11

10x = 22

x = 22 / 10

x = 2.2

Rate of slow hiker = 2.2 mph

Rate of fat hike = x + 2.2 = 2.2 + 2.2 = 4.4 moj
