There are 15 plates and each plate is either 7 or 12 inches diameter. which systems of equations do you use to find the number of 7 inch plates, x and 12 inch plates, y

The equation  is x + y = 15

Step-by-step explanation:

It is given that,

There are 15 plates and each plate is either 7 or 12 inches diameter.

Let the number of 7 inch plates be x and 12 inch plates be y

To find the equation

Total number of plates = 15

By using the given information, we can write

x + y = 15

Therefore the equation is x + y = 15

i think there was a typo. you wrote pat brings 3 quarts of ice-cream to the party. each serving of ice-cream is 1 6 quart. how many total servings of ice-cream does pat bring to the party? i think the bold is supposed to be 1/6. so 1 quart of ice cream = 6 servings. 6 * 3 = 18.
