How do i solve for x and y in 8y+17+7x=180?

You should solve it using system. because we have two unknown values here.

the first equation should be

8y + 17 = 180

the second

17 + 7x = 180

The 4.2 kilograms bag

Step-by-step explanation: First of all, the average month has 30 days, so we want to make sure that Paige can feed her dog for at least a month, or 30 days.

First, multiply the amount Paige will feed her dog per day, 0.12 kilograms by 30 to see the total amount of kilograms she will need to feed her dog.

0.12 x 30 = 3.6 kilograms. So, Paige will need 3.6 kilograms to feed her dog for a month.

So, Paige will need to buy at least the 4.2 kilogram bag in order to feed her dog for a month because the other two bags don't have enough food. Paige will even have some food left over for a couple of extra days.
