combinations
B)
C) neither permutations nor combinations

The method we could use is Combinations

Option B is correct option.

Step-by-step explanation:

We are given:

A car dealer is parking five new cars at his dealership.  Which of the following methods should be used to count the number of  possible ways to pick two cars to put in the showroom?

A)  permutations

B)  combinations

C) neither permutations nor combinations

First let us see, what is permutation and combinations.

Permutation

A permutation is defined as arranging the objects or numbers in a specific order.

Combinations

Combinations are defined as selecting the objects or numbers from a group  in such a way that the order of the objects is not important.

So, in the given question, we need to pick 2 cars and order of the cars is not important, so we can say that we could use Combinations

Option B is correct option.

6 spoons of sugar for every 21 cups of flour

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
