Its 12 because 4 times 12 is 48 if you add 7 to 48 you get 55
Answer:
First one is c because 3 1/2 - 1/2=3
Second one is also c because 0.9x2=1.8
And third one c is because 2 2/3:3/1=1 1/8
(24, 12) and (36, 0). The least amount of flowering plants occurs when x=2y, and the largest amount occurs when y=0. These two points satisfy both conditions and both sum to 36.
The answer is 48. I'm sorry I can't explain cuz it's a long process
