Answer:

x=5

Step-by-step explanation:

these two angles are the same so set both equations equal to each other and solve for x.

$23x-5=21x+5\\23x=21x+10\\2x=10\\x=5$

1. set equations equal to each other

2. add 5 to both sides

3. subtract 21x from both sides

4. divide both sides by 2 to get x alone

5. x=5

Blababa [14]

Answer:

$y=2.5*10^9(0.005^{12 0}) \\\\$

Step-by-step explanation:

The above question is in the form of an exponential decay. The equation for an exponential decay is given by:

$y=ab^x$

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:

$y=2.5*10^9(0.005^x)\\\\After\ ten\ years(x=10*12\ months=120\ months):\\\\y=2.5*10^9(0.005^{12 0}) \\\\$
