How many solutions exist for the system of equations below? (3x+y=18
(3x+y=16
none
one
two
infinitely many

Step-by-step explanation:

3x + y = 18 and 3x + y = 16

=> 18 = 3x + y = 16.

However the equality 18 = 16 is false for any real values of x and y. Hence there are no real solutions.

7

i'm assuming you need to figure out how many campers go into each tent.

i got the answer by:

28/4=7  

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.
