How do you solve x+6/11=10/11

laiz [17]

Answer:

Step-by-step explanation:

x+6/11=10/11

This is a linear equation, because x has no power, so it will be solved by making x the subject of the equation.

Make x the subject

x+6/11=10/11

x=-6/11+10/11

x=10/11-6/11

Since both fractions have the same denominator, the LCM remains 11

x=(10-6)/11

x=4/11

To check if the answer is correct, we substitute x for 4/11 in the equation. And both sides of the equation must be equal

x+6/11=10/11

4/11+6/11=10/11

(4+6)/11=10/11

10/11=10/11

The Lacrosse booster club is holding a raffle for a fundraiser. They will sell 100 tickets for $5 each and select 4 winners. All

Nadusha1986 [10]

Answer:

<h2>There are 3,921,225 ways to select the winners.</h2>

Step-by-step explanation:

This problem is about combinations with no repetitions, because the same person can't win four times. It's a combinaction because the order of winning doesn't really matter.

Combinations without repetitions are defined as

$C_{n}^{r} =\frac{n!}{r!(n-r)!}$

Where $n=100$ and $r=4$ .

Replacing values, we have

$C_{100}^{4} =\frac{100!}{4!(100-4)!}=\frac{100!}{4! 96!}=\frac{100 \times 99 \times 98 \times 97 \times 96!}{4! \times 96!}= \frac{94,109,400}{24}= 3,921,225$

Therefore, there are 3,921,225 ways to select the winners.

Additionally, as you can imagine, the probability of winning is extremely low, it would be 3,921,225 to 1.
