<h3>What is the combination formula?</h3>

Each of the different groups or selections can be formed by taking some or all of a number of objects, irrespective of their arrangments is called a combination.

^mC_k = \dfrac{m!}{k! \times (m-k)!}

A soccer team consisting of 3 forwards, 4 midfield players, and 3 defensive players, if the players are chosen from 8 forwards, 6 midfield players and 8 defensive players

Since they are independent of each other, the total number of combinations will be;

^mC_k = \dfrac{8!}{3! \times (5)!}  \times \dfrac{6!}{4! \times (2)!} \times \dfrac{8!}{3! \times (5)!} \\\\^mC_k =47,040

Hence, There are 47,040 ways to form a soccer team.

Translate the sentence into an equation, then solve the
Oduvanchick [21]

Answer:

The equation is: \frac{x-7}{5} = 13 and the number is 72.

Step-by-step explanation:

We have to use mathematical notation to convert the given statement into an equation. As we don't know the exact value of number, we have to use a variable in place of the number.

Let x be the required number then

"A number decreased by 7"

x-7

"and then  divided by 5"

\frac{x-7}{5}

" is 13."

\frac{x-7}{5} = 13

For solving, multiplying both sides of equation by "5"

\frac{x-7}{5} * 5 = 13*5\\x-7 = 65

Adding 7 on both sides of equation

x-7+7 = 65+7\\x = 72

Hence,

The equation is: \frac{x-7}{5} = 13 and the number is 72.
