Answer:
C
Step-by-step explanation:
So I'm going to subtract (x+7)/(x+3) on both sides:
(x-6)/(x+5)-(x+7)/(x+3)>=0
Now I'm going to find a common denominator which is (x+5)(x+3).
[(x-6)(x+3)-(x+7)(x+5)]/[(x+5)(x+3)]>=0
Now I just have a lot of simplifying to do:
[x^2+3x-6x-18-(x^2+5x+7x+35)]/(x^2+3x+5x+15)>=0
[-3x-18-12x-35]/(x^2+8x+15)>=0
[-15x-53]/[x^2+8x+15]>=0

Answer:
B
Step-by-step explanation:
the first fish tank has 100 gallons of water and 1 gallon is removed every hour which makes 100-h
the second tank has 40 gallons in it and 2 gallons are added every hour which makes 40+2h
after 20 hours the second tank will have more gallons than the first tank
this means that 40+2h would be greater than 100-h since it's also asking you "After how many hours will the first tank have less water than the second?"
