Answer:

Five bags of dog food costs $21.25.

Step-by-step explanation:

We can solve using proportions.

$\frac{6 \: bags}{25.50 \: dollars} = \frac{5 \: bags}{x} \\ \\ \frac{127.5}{6} = \frac{6x}{6} \\ \\ 21.25 = x \\ 21.25 \: dollars = x$

Answer:

4x + 5y = 20

Step-by-step explanation:

4x + 5y = 20

5y = -4x + 20 (Subtract 4x to isolate 5y. Put the 4x in front of the 20)

y = $-\frac{4}{5}x$ + 4 (Divide all by 5 to isolate y)

And then it's done and in slope-intercept form

$-1< -\frac{4}{5} < 0$ or $-\frac{4}{5}$ is greater than -1 but less than 0

I hope this helped :)
