Answer:
n=6
Step-by-step explanation:
6n = 30 + 3(n – 4)
Distribute
6n =30 +3n -12
Combine like terms
6n = 18 +3n
Subtract 3n from each side
6n-3n = 18+3n-3n
3n = 18
Divide each side by 3
3n/3 =18/3
n =6

Answer:
I believe the answer is the first one [4/7 ,6/7].
I used process of elimination
The fourth one is unreasonable and impossible.
The third one is more than the weekly requirement.
The second one is the weekly requirement.
The first one would have to be in reason because of that.
The required equation is m = 100-5c.
An equation is a mathematical statement that shows that two mathematical expressions are equal.
Given that, Grace has $100. She is buying charms for her bracelet that cost $5 each.
Let, she buys c charms for her bracelets,
Therefore, the equations become,
m = 100-5c
Where, m is money is she left with.
Hence, the required equation is m = 100-5c.
