Abasketball player’s free-throw percentage is the ratio of the number of successful shots made to the number of shots attempted. a basketball player has made 13 of the first 20 free throws she has attempted this season. which rational expression can be used to find the free throw percentage for the season if she successfully makes her next x free-throw attempts?

is the rational expression.

Step-by-step explanation:

Basketball player made 13 of the first 20 free throws she attempted this season.

Next x successful free throw attempts means total successful attempts made by player = 13 + x

and total free attempts = 20 + x

Since free throw percentage is the ratio of successful shots made to the number of shots attempted.

Therefore, ratio will be =

Therefore the rational expression used is

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
