Answer:
1, -4.5
Step-by-step explanation:
What do you mean by estimating the solution?
y=-6x+4
x-4(-6x+4)=19
x+24x-16=19
25x=25
x=1
1-4y=19
-4y=18
y=-4.5
Answer:
I think its C but I'm not too sure.
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?"
Answer:
The correct answer is 20%
Hope this helped! :)
