Evaluate the expression x=-15 -6x-2

Let's solve your equation step-by-step.

x=−15−6x−2

Step 1: Simplify both sides of the equation.

x=−15−6x−2

x=−15+−6x+−2

x=(−6x)+(−15+−2)(Combine Like Terms)

x=−6x+−17

x=−6x−17

Step 2: Add 6x to both sides.

x+6x=−6x−17+6x

7x=−17

Step 3: Divide both sides by 7.

7x/7= -17/7

x= -17/7

x=  -17/7

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
