Hello! For this problem, we have to use the distributive property. So we do 5 * x and 5 * 6. When we do that, we get 5x - 30. The answer is C: 5x - 30.
The amount of water decreases
pints in 12 weeks.
Solution:
The amount of water decreases in 7 weeks =
pints
The amount of water decreases each week is same.
Let us first change the mixed fraction into improper fraction.
pints =
pints
The amount of water decreases in 1 week



So, the amount of water decreases in 1 week is
pints.
The amount of water decreases in 12 week



pints
Hence the amount of water decreases
pints in 12 weeks.

As we have to solve for b, it means we have to isolate b
So first of all subtract
from both sides
So we get

Now we need b , but its b^2 , so we can take square root on both sides.
taking square roots on both sides

Hence option B is correct
