There is a drought and the oak tree population is decreasing at the rate of 3% per year. If the population continues to decrease at the same rate, how long will it take for the population to be half of what it is? If necessary, round your answer to the nearest tenth.

the answers are in the images, i received 100% on this assignment. hope this !

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w

so 75 people in the room, 3 more enter so

75 + 3 = 78 so then 2 leave so

75 + 3 = 78 - 2 = 76

then since im not sure what beat up means but im guessing they stayed because it doesnt sya they left so

hope i have a great day!
