Jan had $126. she spent 1/6 of her money on her makeup and 2/3 of her money on shoes. How Much does Jan have left?
Jobisdone [24]

She has 1/6 of her money left, which is $21. 

2/3=4/6, so 4/6 + 1/6=5/6, which means she has 1/6 left.  Divide $126 by 6 and you get $21.

Find the value of n that satisfies 2(n+1)! + 6n! = 3(n+1), where $n! = n\cdot (n-1)\cdot (n-2) \cdots 2\cdot 1$.
Murrr4er [49]

Answer:

n = 5

Step-by-step explanation:

Given

2(n+1)! + 6n! = 3(n+1)!

Required

Find n

Simplify (n + 1)!

2(n+1)*n! + 6n! = 3(n+1)*n!

Factorize

n![2(n+1) + 6] = 3(n+1)*n!

Divide both sides by n!

2(n+1) + 6 = 3(n+1)

Open brackets

2n + 2 + 6 = 3n + 3

2n + 8 = 3n + 3

Collect like terms

2n - 3n = 3 -8

-n =-5

Multiply both sides by -1

n = 5
