Answer:
See explanation below
Step-by-step explanation:
a + b = 0
The additive identity establishes that if you add a real number to zero, then you get the same real number back.
The additive inverse of a number x is -x (because x + (-x) = 0)
a+b = 0, but by the additive identity we can add -a (the additive inverse of a) to both sides of the equation:
a + b - a = 0 - a
a + b - a = -a (Now, using the Cancellation property we can cancel a and -a on the left side)
b = -a
Answer:
45
Step-by-step explanation:
Decreasing by 25% means that there is 25% less of last years amount or 0.25x less. It also means that this year there is only 75% of what was last year actually in the lake or 0.75x. Since last year, there were 60 fish, this means this year there is 0.75(60) = 45. This year has 45 fish.
