2 1/2 ÷ 1/4 reduce
5/2 × 4/1 = 20/2
20 ÷ 2 = 10 pounds of flour per sugar
(I'm not very good at math so this might be wrong)
3x + y = -3
-2x + y = 7
Use elimination method
Subtract both equations
5x = -10, x = -2
Plug in -2 for x (any equation)
3(-2) + y = -3
-6 + y = -3
y = 3
Solution: x = -2, y = 3
Or as a coordinate: (-2, 3)

Step-by-step explanation:
Add the basketball and airpump together and subtract from 50
The ratio of the trout with tags that are caught and the total trout with tags is first calculated.
r = 12 trout / 180 trout = 1/15
Then, we divide the number of trouts caught without tag by the value obtained above.
N = (48 - 12) / (1/15) = 540
Then, we add the number obtained above and 180.
T = 540 + 180 = 720
ANSWER: 720
