M = 72
Your main goal in this equation is to isolate m or in other words leave m alone in one side of the equality.
All you need to do is multiply 4 in both sides for you to eliminate the denominator attached to m.
Saying this,
(M/4)(4) = (18)(4)
M = 72
Answer: For a fence that has 18 posts he needs 36 rails.
Step-by-step explanation:
Hi, to answer this question we have to use proportions:
Each section use 3 vertical fence post and 6 horizontal rails
The proportion is = 3 post /6 rails
For 18 posts:
18 posts / x rails.
3 /6 = 18 /x
Solving for x:
x = 18 / (3/6)
x = 36 rails
For a fence that has 18 posts he needs 36 rails.
Feel free to ask for more if needed or if you did not understand something.
The exponent would be 3 because u have to multiply 2 three times to get 8
