How many different strings can be formed by rearranging the letters in the word DCDCD?
Natali [406]
<h2>Answer:</h2>

The different strings which can be formed by rearranging the letters in the word DCDCD are:

                                     10

<h2>Step-by-step explanation:</h2>

We are asked to find the different number of arrangements that may be me made in the word:

                               DCDCD

There are a total of 5 words such that D is repeated 3 times and C is repeated two times.

Hence, the total number of ways of arrangement is given by:

=\dfrac{5!}{3!\times 2!}\\\\=\dfrac{5\times 4\times 3!}{3!\times 2!}\\\\=\dfrac{5\times 4}{2!}\\\\=\dfrac{5\times 4}{2}\\\\=10

Hence, the total number of ways are:  10

Substitution<br> 2x-2y=14 <br> x-y=2
LiRa [457]

Answer:

<h3>NO solution</h3>

Step-by-step explanation:

You must isolate by substitution to solve this problem.

\sf{2x-2y=14 \quad x-y=2}

Separate by x and y from one side of the equation.

Solve with 2x-2y=14, first.

2x-2y=14 which is equal to x=7+y.

Substitute x=7+y.

\sf{7+y-y=2}

Then you solve it.

You only need to cross out the variable y.

<u>7=2</u>

<u>NO solution.</u>

Therefore, a solution cannot be found.

I hope this helps! Let me know if my answer is wrong or not.
