You could say 2 1/4 = 3/8p

2 1/4 is the total height of the stack, which is equal to 3/8 (thickness of each piece of paper) multiplied by p (placeholder for the total pieces of paper).

By solving for p, we are solving for the number of pieces of paper that will give us a stacked height of 2 1/4 inches.

We can solve this equation by dividing both sides by 3/8, giving us p = 6

Hope this helps!

Sorry to hear this! Web2.0 calc is a free service, so it won't be as good as paid services such as Chegg or Study.com. From what I've seen, the mods and community here try their best to answer questions as quickly as possible! I've been around here roughly since 2016 (lost my other account, created this one recently), so feel to reach out to me, or one of the moderators!

We can use the Binomial Theorem here! (although you can also use the Pascal's Triangle method, I just prefer to use this)

(6!/(2!6-2)!)(2x)^4(1/2)^2 = 15*16x*1/4 = 60x^4

So therefore our coefficient is 60!

Hope this helps!
