Answer:
-10
Step-by-step explanation:
let the number=x
5(x+12)=10
x+12=10/5=2
x=2-12=-10

Answer:
Step-by-step explanation:
The above question is in the form of an exponential decay. The equation for an exponential decay is given by:
where y and x are variables, b < 1, a is the initial value of y (that is the value of y when x = 0).
Let y represent the number of trees left and x represent the number of months. Given that there is currently 2.5 billion trees, therefore a = 2.5 * 10⁹, b = 0.5% = 0.005. The equations becomes:
I believe the answer is A. 20, 30, 40 is NOT a pythagorean triple.
