81+7x=81 what does x equal?

cupoosta [38]

So to start off here is the question being asked:
81+7x=81
The first thing we are going to do is simplify both sides of the equation:
7x+81=81
Second thing to do is subtract 81 from both sides so:
7x+81−81=81−81
The final thing to do is divide both sides by 7:
7x/7=0/7
The final answer is:
x=0

I hope this helps! :)

What is the total amount and the amount of interest earned on $6,500 at 6% for 25 years?

Deffense [45]

Here's the equation for one year:
0.06(6500) + 6500
But because it is 25 years:
25(0.06(6500)) + 6500
1.5(6500) + 6500
We can make it simpler:
2.5(6500)
The total amount is $16350

$sin(x)=\frac{32}{58}$
