Answer:

y=1X

Step-by-step explanation:

This is because the distance over the money made over the days worked is 2/2 which simplifies to 1 so that would be the one x. then the y intercept is found on the y axis where does the line cross the y axis? this would be at zero so you do not need to put that in the equation

ivolga24 [154]

Answer:

The athlete will run 200 kilometers.

A atleta percorrerá 200 quilômetros no total.

Step-by-step explanation:

She will run x kilometers.

She has already run 5/8 of the distance(5/8 of x), and still needs to run 75 kilometers.

So

\frac{5x}{8} + 75 = x

x - \frac{5x}{8} = 75

\frac{8x - 5x}{8} = 75

3x = 8*75

x = \frac{8*75}{3}

x = 200

The athlete will run 200 kilometers.

A atleta percorrerá 200 quilômetros no total.
