ZanzabumX [31]

Answer:

x = 8

Step-by-step explanation:

6x - 3 = 5x + 5

Move variable to the left hand side and change their sign.

  • \sf \: 6x - 5x - 3 = 5

Calculate like terms.

  • x - 3 = 5.

Move constant to the right hand side and change their sign.

  • x = 5 + 3
  • x = 8

<u>Check our answer :-</u>

6x -3 = 5x + 5

plug the 8 as x.

  • 6 ( 8 ) - 3 = 5 ( 8 ) + 5
  • 48 - 3 = 40 + 5
  • 45 = 45

LHS = RHS

A man walking on a railroad bridge is 2/5 of the way along the bridge when he notices a train at a distance approaching at the c
makkiz [27]

Answer:

The Man needs to run at 9 mph

Step-by-step explanation:

Let M stand for the man's speed in mph.  When the man  

runs toward point A, the relative speed of the train with respect  

to the man is the train's speed plus the man's speed (45 + M).  

When he runs toward point B, the relative speed of the train is the  

train's speed minus the man's speed (45 - M).

When he runs toward the train the distance he covers is 2 units.  

When he runs in the direction of the train the distance he covers  

is 3 units. We can now write that the ratio of the relative speed  

of the train when he is running toward point A to the relative speed  

of the train when he is running toward point B, is equal to the  

inverse ratio of the two distance units or

              (45 + M)          3

              -----------  =      ---

              (45 - M)          2

          90+2 M=135-3 M

⇒5 M = 45

⇒ M = 9 mph

The Man needs to run at 9 mph
