Answer:

Step-by-step explanation:

Let x and y represent the numbers of small and large cars washed, respectively.

We know that:

$4.50x + $8y = $420

But we don't know the relationship between x and y.  We need more information (e.g., they washed twice as many small cars and large).  Otherwise we have one equation and two unknowns.  Since there are two unknowns, we can't determine a "slope" of the line.  With all the water and soap, the most we could possibly say it will be a slippery slope.

The winner of a race ran the distance in 45s at an average speed of 9.6 m/s. The runner who came in last finished and 48 seconds
RSB [31]

Answer:

The answer to your question is speed = 9 m/s

Step-by-step explanation:

Data

Winner                                 Last runner

time = 45 s                           time = 48 s

speed = 9.6 m/s

Process

1) Calculate the distance they ran using the data of the winner

      speed = distance / time

-Solve for distance

      distance = speed x time

-Substitution

      distance = (9.6)(45)

-Result

      distance = 432 m

2.- Calculate the speed of the last runner

-Substitution

      speed = 432/48

-Result

     speed = 9 m/s
