The sum of three consecutive numbers is 84. Write and solve a math expression in terms of n for the smallest of the three numbers. Include parentheses.

 Required expression :  

Smallest number = 27

Step-by-step explanation:

Let the three consecutive number be n-1 , n , n+1 .

Since , the sum of three consecutive numbers is 84.

Remove parenthesis

Simplify

Divide both sides by 3, we get

That means the three consecutive numbers would be (28-1) , 28 , (28+1)

i.e. 27 , 28 , 29.

Hence, the smallest number is 27.

this is a very good question

step-by-step explanation:

i got a hair cut today from my mom not to flex just to flex kim jon un is one rad fellow i'd say you'd need to take the hairline in kinda like a box shape like someone rammed a lego brick into your head. from there you really need to take the top up keeping with that boxy aesthetic, finally coat the whole thing with gel if your country economics are failing or whatever you can just coat it with the starving children's food rations. about 5 orphans per strand is a good ratio. good luck with the fresh cut my dude

2(2x + 3) = -4 + 2(2x + 5)

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 6

4x - 6 + 6 = 4x - 6 + 6

4x = 4x

x = x
