The water level of lake waxahatchie changes an average of - 5/12 of an inch every three years. based on the rate above, how much will the water level change after one year?

a −15/12

b 15/12

c −5/36

d 5/36

I Think that the answer is A。

Step-by-step explanation:

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
