2(5-3v)+9v=28 step by step please
Irina-Kira [14]
First, distribute the 2 across the parenthesis.
10-3v+9v=28
Combine like terms on the left.
10+6v=28
Start to get the numbers on the right and the v alone on the left by moving the 10 to the right.
6v=28-10
6v=18
Divide to get the v alone.
v=3

Hope that helps.

-13.2 + 0.5x > 0.1x + 20
Georgia [21]
First add 13.2 to both sides to get 0.5x > 0.1x + 33.2.
Then subtract 0.1x from both sides to get 0.4x > 33.2.
Lastly, divide each side by 0.4 to get a final answer of x > 83.
Hope this helps!

How do i solve ∑(n→∞)〖4.594 ln(n)- 0.8129〗
Vitek1552 [10]

For every n \geq 2, we have

4.594\log(n)-0.8129>1

So, negletting the first term, each term of the sum is greater than 1, which implies

\displaystyle \sum_{n=2}^\infty 4.594\log(n)-0.8129> \sum_{n=1}^\infty 1 =\infty

Which means that the series diverges.
