Solve -5w = -80 for w.

 The correct answer is:  " 16 " .

     →   " w = 16 "  .

Step-by-step explanation:

Given:

 -5w = -80 ;   Solve for "w" ;.

Divide each side of the equation by:  " - 5 " ;  

  to isolate "w"  on one side of the equation;

   & to solve for "w" ;

- 5w / -5 = -80 / -5 ;

to get:

    w = 16 .

Hope this helps!

step-by-step explanation:

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
