Answer:

$\boxed{\boxed{\sf x=-6}}$

Step-by-step explanation:

$\sf \cfrac{9-x}{5}=3$

$\sf \cfrac{5\left(9-x\right)}{5}=3\times \:5$

$\sf 9-x=15$

$\sf 9-x-9=15-9$

$\sf -x=6$

$\sf \cfrac{-x}{-1}=\cfrac{6}{-1}$

$\sf x=-6$

Are the graphs of the lines in the pair parallel? Explain.

To make it easier turn this equation into a slope. To do that you must get "y" by itself on one side of the equal sign. The "y" have to be positive. Then plot it out. Enter the "x" (1 for example) in the equation and solve to get "y". Then use the ordered pair to plot out the slope. Then you find a coefficient of "x" that matches the one in this equation and plot that out. If it's parallel then it's right. :)

4.2kg

Step-by-step explanation:

She feeds her dog .12 a day, so for a month, I would multiply by 30 or 31

(both will give you the same answer).

After doing that , you get 3.6 (I multiplied by 30)

The other 2 options are less than that.
