Hey there!

Explanation:

First, you had to do is add by 13 from both sides of an equation.

3a-13+13=47+13

Then, simplify or add by the numbers.

47+13=60

3a=60

Next, you can also divide by 3 from both sides of an equation.

\frac{3a}{3}=\frac{60}{3}

And finally, simplify and divide by the numbers,

60/3=20

*The answer must have a positive sign.*

\boxed{a=20}

Hope this helps!

A company’s stock was selling at $25 a share a month later it was selling at $30 a share what is the percent increase
rjkz [21]

Answer:

20% increase

Step-by-step explanation:

To find the percent increase, you can divide the increase value by the original: 30/25 = 1.2 --> 120%. Next, since they ask for the percent of increase, you can subtract 1 or 100% from your answer which would give you a final answer of 20% increase.
