Question

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)

Answer 1

Option C -
`P=8m`

Explanation:

Given : Formula
`P=9m-3n` If you know that n is
`(1)/(3)` of m.

To find : How could you rewrite this formula?

Solution :

Step 1 - Write the formula,

`P=9m-3n`

Step 2 - Substitute,
`n=(1)/(3)m`

`P=9m-3((1)/(3)m)`

Step 3 - Solve,

`P=9m-m`

`P=8m`

Therefore, The formula can be re-write as
`P=8m`

So, Option C is correct.
