To figure this out, always divide y by x in each table. All of the values have to be equal or the table isn’t proportional.

In this case, the last choice is proportional.

If 3 quarts of paint are needed for 50 ft of fence, how many quarts are needed for 300 ft of fence?

Zina [86]

Answer:

Step-by-step explanation:

First, you would do a proportion

$\frac{3}{50}$ = $\frac{x}{300}$

Then you would cross multiply, getting 50x=900.

After that, you would do 900/50, which is 18.

Each month, Diana donates the same amount of money to a charity.

prisoha [69]

Start by making an equation.

D is your variable.

12d=1500

Then, divide each side by 12 because there are 12 months.

12d=1500
—- ——
12. 12

d=125

Diana donates $125 per month to a charity. This is because when you have a yearly sum that is paid per month, but you don’t know the per month rate, you divide the yearly amount by 12 because there are 12 months.

I really hope this helps and you get a good grade!!
