Answer:
y = (1/2)x - 3
Let's take x = 1, 2, 3. Substitute x into y = (1/2)x - 3 to find out y.
x = 1 => y = (1/2)(1) - 3 = -5/2
x = 2 => y = (1/2)(2) - 3 = -2
x = 3 => y = (1/2)(3) - 3 = -3/2
=> 3 solutions are: (1, -5/2), (2, -2), and (3, -3/2)

Answer:
14 cows
46 turkeys
Step-by-step explanation:
If all the animals were turkeys, there would be 120 legs. There are 28 more than that. Replacing a turkey with a cow adds 2 legs, so there must be 14 such replacements.
There are 14 cows and 46 turkeys.
_____
Check
14×4 + 46×2 = 56 + 92 = 148 . . . . legs
14 + 46 = 60 . . . . . . heads
Approximately 10 weeks. To be specific, 9.71 of a week.
Add all the numbers and divide it by the number of numbers --> (7+9+6+15+22+25+31) = 115
115/7 = 16.4 --> conventional rounding would mean the answer would be 16
