Step-by-step explanation:
Remark
The two angles with x in their numerical value are added to get 108
Solution
10x + 2 + 4x + 8 = 108 Collect like terms
14x + 10 = 108 Subtract l0 from both sides.
14x + 10 -10 = 108 - 10 Collect like terms
14x = 98 Divide by 14
x = 98/14
x = 7
Answer:
The statement is correct
see the explanation
Step-by-step explanation:
we know that
The equation of a exponential growth function is equal to
![y=a(1+r)^x](https://tex.z-dn.net/?f=y%3Da%281%2Br%29%5Ex)
where
y is the area covered by the plant in percentage
x is the time in years since 2000
r is the rate of change
a is the initial value
In this problem we have
![r=200\%=200/100=2](https://tex.z-dn.net/?f=r%3D200%5C%25%3D200%2F100%3D2)
![a=0.2\%](https://tex.z-dn.net/?f=a%3D0.2%5C%25)
substitute the values
![y=0.2(1+2)^x](https://tex.z-dn.net/?f=y%3D0.2%281%2B2%29%5Ex)
![y=0.2(3)^x](https://tex.z-dn.net/?f=y%3D0.2%283%29%5Ex)
In the year 2005
![x=2005-2000=5\ years](https://tex.z-dn.net/?f=x%3D2005-2000%3D5%5C%20years)
substitute the value of x in the exponential function
![y=0.2(3)^5=48.6\%](https://tex.z-dn.net/?f=y%3D0.2%283%29%5E5%3D48.6%5C%25)
48.6% is about 50%
therefore
The statement is correct
Answer:
2(3-4a)+5(a-7)
