Each can of corn costs $0.89
Work: 10.68/12 = .89
Therefore each can of corn costs 89 cents.
3x + 3y = 27
3x - 3y = -11
------------------add
6x = 16
x = 16/6 which reduces to 8/3
3x + 3y = 27
3(8/3) + 3y = 27
8 + 3y = 27
3y = 27 - 8
3y = 19
y = 19/3
solution is (8/3, 19/3)

Answer:
60, 57, 54, 51, ...
Step-by-step explanation:
The general term of an arithmetic sequence is ...
an = a1 +d(n -1)
We would like to find the first term (a1) and the common difference (d). We can use the two given terms to find these parameters.
a10 = 33 = a1 +d(10 -1)
a22 = -3 = a1 +d(22 -1)
Subtracting the first equation from the second, we get ...
(-3) -(33) = (a1 +21d) -(a1 +9d)
-36 = 12d
-3 = d
Using this value in the first equation, we can find a1.
33 = a1 +9(-3) = a1 -27
60 = a1 . . . . . . . . . . . . . . add 27 to both sides
So, our sequence has first term 60 and a common difference of -3.
The first 4 terms are ...
60, 57, 54, 51, ...
