5.68x10^11
100=10^2
1 billion=10^9
10^2*10^9=10^11
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:
b. 28x + 8y +2
Step-by-step explanation:
you need to distribute the -2 to all the numbers inside parentheses and then combine like terms.
-2*3x= -6x
-2*12y= -24y
-2*-5= 10 (remember neg times neg = pos)
-2*17= 34x
-2*-16y=32y
-2*4= -8
Now combine like terms
34x-6x= 28x
32y-24y=8y
10-8=2
Write the expression: 28x + 8y +2
