Given : Ketut is organizing a barbecue for his parents. He knows that 13 of his mom’s friends prefer hot dogs and 9 of his dad’s friends prefer hamburgers.

To Find: He organizes a two-way table to determine what he needs to buy. Which describes the variables he can use in the first row and first column of his table?

Solution:

Since we are given that she is organizing a table of meal for parents or their friends .

So, table must include column of parents and choice of meal.

Since we are given that 13 friends is of her mom and 9 friends is of her dad and their meal choices are given .

So, the variables he can use in the first row and first column of his table is parent and meal choice.

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

is there a question here?
