Question

13. Find the value of P if 9P+1/3P = 81.​

Answer 1

Answer:

Step-by-step explanation:

Take p common

P(9+1/3)=81

P(26/3)=81

P = 81×3/26

P= 9.34

Answer 2

Answer:

=> The value of P is $\frac{243}{28}$.

Step-by-step explanation:

Given that:-

$9P+\frac{1}{3} P = 81$

To find:- The value of the expression,

For solving this expression, we must apply the transposition method:

As we have,

=> $9P+\frac{1}{3} P = 81$

Combined as a single fraction,

=> $9P+\frac{P}{3} = 81$

Finding a common denominator,

=> $\frac{3\times 9P}{3}+\frac{P}{3} =81$

Combine fraction with a single fraction,

=> $\frac{3\times 9 P +P}{3} =81$

=> $\frac{27 P +P}{3} =81$

Combine the like terms,

=> $\frac{28P}{3} =81$

Now multiply both sides by $3$, we get

=> 28 P = 243

Now, divide both sides by $28$,

=> $P = \frac{243}{28}$

Hence, the required solution is $\frac{243}{28}$.
