Answer:

Step-by-step explanation:

3x = 25 - 5y

-100 < 5y < 50

-50 < -5y < 100

-25 < 25 - 5y < 125

-8.333 < x < 41.667

41+8+1 = 50

You bike 11.2 miles in 1.4 hours at a steady rate. What equation represents the proportional relationship between the x hour you

Elis [28]

Answer:

$\frac{x}{y}=8$

Step-by-step explanation:

Let the time for which i bike is = x hours

Let the distance traveled in x hours = y miles

Ratio of distance and time will be = x : y

I travel 11.2 miles in 1.4 hours then the ratio of time and the distance traveled will be 1.4 : 11.2 Or 14 : 112

then the ratio of distance and time will be same in both the cases

So equation will be

$\frac{x}{y}=\frac{14}{112}$

$\frac{x}{y}=8$

Therefore, equation representing the proportional relationship will be

$\frac{x}{y}=8$
