I=prt
I interest earned
P principle 4000
R interest rate 0.095
T time270/365
I=4,000×0.095×(270÷365)
I=281.10
Answer:
n=6
Step-by-step explanation:
Given -> -2(n+5)+6n=14
Distributive Property -> -2n-10+6n=14
Combine like terms -> 4n-10=14
Add 10 to both sides -> 4n=24
Divide both sides by 4 -> n=6
So n=6
