X + y = 405
y = 8x
To solve:
Plug the second equation into the first and solve for x.
x + 8x = 405
9x = 405
Divide both sides by 9
x = 45
Use the second equation to find y.
y = 8(45)
y = 360
45 angelfish
360 parrotfish
49+1+16=66
66/9=22/3
22/3 can also be expressed as 6 2/3
A is the answer hope this helps
But sometimes things can grow (or the opposite: decay) exponentially, at least for a while.
So we have a generally useful formula:
y(t) = a × ekt
Where y(t) = value at time "t"
a = value at the start
k = rate of growth (when >0) or decay (when <0)
t = time
