Question

Each side of a regular pentagon is m + 10 inches. The formula for finding the perimeter of the pentagon is shown below. P = 5 (m +10) Which equation shows this formula solved for m? A. M = P − 5 / 10 B. M = 5P − 50 C. M = P − 50 / 5 D. M = P/5 − 50

Answer 1

D.) m=P−505

Explanation:

Answer 2

m = p/5 -10

m= (p-50)/5

Explanation:

What we practically want to here is to make m the subject of the formula.

Start by opening the brackets

P = 5m + 50

P-50 = 5m

Divide through by 5

(P-50)/5 = m

P/5 -50/5 = m

P/5 -10 = m

The option that looks probable is C ; M = (P-50)/5
