1/9 - 5/6
Convert both of them into denominators of 18.
2/18 - 15/18
Subtract the numerators and keep the denominator:
-13/18
The function:
f ( x ) = x * 0.965^t
where x is the initial amount and t is the number of the years
80 = x * 0.965^3
80 = x * 0.89632
x = 80 : 0.89632 ≈ 89
Answer:
The initial amount of animals was 89.
Answer : <span>10797060.8144
</span>2545.24 x 4242.06 = <span>10797060.7944
</span>10797060.7944 + 2/100 = 10797060.8144
If you would like to solve 2 * (7 - x) = 3 * (x + 3), you can do this using the following steps:
2 * (7 - x) = 3 * (x + 3<span>)
</span>2 * 7 - 2 * x = 3 * x + 3 * 3
14 - 2 * x = 3 * x + 9
14 - 9 = 3 * x + 2 * x
5 = 5 * x
x = 1
The correct result would be x = 1.
I'd say A, since there, all the operations are the opposite from the original function.
