So, say order mattered. If we had x toppings and we only wanted groups of two different toppings, we would have x toppings for the first option, and x-1 toppings for the second option since we've already used a topping. Using the multiplication rule that would give us x(x-1) different groups, if order mattered, which is written as:
So, in this specific problem order does not matter. We see that we've overcounted because for every pair of toppings we have, they can be reordered 2!=2 ways. So that means we must divide by two to get:
Which is written as:
Solving the inequality we get value of x:
Step-by-step explanation:
We need to solve the inequality and find value of x.
Solving:
Multiplying -3 with the terms inside the bracket
Converting mixed fraction into improper fraction:
Adding 11.98x on both sides
Subtracting 24.6 on both sides:
Divide both sides by -0.02 and reverse the inequality i.e < sign is changed to > due to division of (-) sign.
So, solving the inequality we get value of x:
