suppose you're given the formula P = 9m – 3n. If you know that n is 1⁄3 of m, how could you rewrite this formula?


A. P = m

B. P = 2(m – n) ASAp


C. P = 8m

D. P = 3(m – 2n)

Respuesta :

Answer:

Option C - [tex]P=8m[/tex]

Step-by-step explanation:

Given : Formula [tex]P=9m-3n[/tex] If you know that n is [tex]\frac{1}{3}[/tex] of m.

To find : How could you rewrite this formula?

Solution :  

Step 1 - Write the formula,

[tex]P=9m-3n[/tex]

Step 2 - Substitute, [tex]n=\frac{1}{3}m[/tex]

[tex]P=9m-3(\frac{1}{3}m)[/tex]

Step 3 - Solve,

[tex]P=9m-m[/tex]

[tex]P=8m[/tex]

Therefore, The formula can be re-write as [tex]P=8m[/tex]

So, Option C is correct.
