SOLUTION

The given expression is:

$-5\sqrt[]{147\times r^{13}\times s^8}$

Rewrite the expression

$-5\sqrt[]{49\times3\times r^{12}\times r^1\times s^{4\times2}}$

This further give

$\begin{gathered} -5\sqrt[]{49\times3\times(r^6)^2\times r^1\times(s^4)^2} \\ =-5\times7\times r^6\times s^4\sqrt[]{3\times r} \\ =-35r^6s^4\sqrt[]{3r} \end{gathered}$

Therefore, the solution is

$-35r^6s^4\sqrt[]{3r}$

A total of 399 tickets were sold for the school play. They were either adult tickets or student tickets. The number of students

weqwewe [10]

133 adult tickets were sold.

Step-by-step explanation:

Given,

Total tickets sold for school play = 399

Let,

x represent the number of children tickets sold.

y represent the number of adult tickets sold.

According to given statement;

x+y=399 Eqn 1

x = 2y Eqn 2

Putting value of x from Eqn 2 in Eqn 1

$2y+y=399\\3y=399$

Dividing both sides by 3

$\frac{3y}{3}=\frac{399}{3}\\y=133$

133 adult tickets were sold.
