54 boo . Divide 189 by 7 then multiply by 2 which is 54
Answer:
Step-by-step explanation:
3x+13+x-8+x=180
collect like terms

5x=175
divide both side by 5
x=35
The area of forest after 5 years is 2846.93 square kilometer
<em><u>Solution:</u></em>
Given that, A certain forest covers an area of 4500 square kilometer
Suppose that each year this area decreases by 8.75%
To find: Area after 5 years
<em><u>The decrease function is given as:</u></em>

Where,
y is the value after t years
A = initial amount
r = decreasing rate in decimal
t is the number of years
Here in this sum,
A = 4500
t = 5 years

<em><u>Substituting the values in formula,
</u></em>

Thus the area of forest after 5 years is 2846.93 square kilometer
