Answer:

x=3

Step-by-step explanation:

1) 3(x+7)=6(x+2)

2)Multiply the number on the outside by the numbers on the inside

3x+21 =6x+12

3)Subtract 3x from 6x. When you do that it cancels out itself on the side it came from leaving you with only 21 one that side.

21=3x+12

4)Subtract 12 from 21. When you do that it cancels out itself on the side it came from leaving you with only 3x on that side.

9=3x

5) Divide 3x from both sides that will cancel out the x leaving you with only 1x and it will turn the 9 into 3.

9/3x=3x/3x

x=3

A traveler traveled for 6 hours and covered a distance of 520 km. He traveled the first 260 km by car, and the rest of the way b

Shkiper50 [21]

Answer:

57.78 km/hr

Step-by-step explanation:

Total time taken, t = 6 hours

Total distance covered, d = 520 km

Distance by car = 260

Distance by train = 520 - 260 = 260 km

Train speed = x

Car speed = 2x

Average speed speed = 3x /2

Speed = distance / time

1.5x = 520 / 6

9x = 520

x = 520 / 9

x = 57.777

Average speed of train = 57.78 km/hr
