Correct answer gets brainliest

6

Step-by-step explanation:

all you gotta do is plug 1/3 onto the equation.

if you are allowed to use a calculator then use desmos. if not then break it into parts.

54*(1/3)^2

1/3*1/3=1/9

then you get: 54*1/9

then you get 54/9 which is division

final answer is 6

not solvable

step-by-step explanation:

we need more information, or at least an

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
