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?"

Step-by-step explanation:
add 4 to 6 and take away 3
Answer: 4/6
1. Subtract 8/6 by 4/6.
4/6 + 4/6 = 8 is the same as:
<em>Notice: You don't change the denominator if your adding or subtracting.</em>
<em>That's why 4 + 4 = 8 is the same as 4/6 + 4/6.</em>

Answer:
m<A=94
Step-by-step explanation:
(2x+10)+(2x+2)=180
4x+12=180
-12 -12
4x=168
/4 /4
x=42
m<A= 2x+10
m<A=2(42)+10
m<A=84+10
m<A=94
Check:
Add m<A and m<B which should equal 180.
m<B=2x+2
m<B=2(42)+2
m<B=84+2
m<B=86
94+86=180
