Answer:
x= 6
Step-by-step explanation:
Step 1: Write equation
2x - 5 = 7
Step 2: Solve for <em>x</em>
<u>Add 5 to both sides:</u> 2x = 12
<u>Divide both sides by 2:</u> x= 6
<u />
Step 3: Check
<em>Plug in x to verify if it's a solution.</em>
2(6) - 5 = 7
12 - 5 = 7
7 = 7
If 10% of songs represents 6 songs,
then 100% of songs represents (100 * 6) / 10 = 60 songs
The playlist has a total of 60 songs.
The equation to solve this should be x+3x=60

Answer:
(f+g)(x) = 3x^2 + x + 1
Explanation:
We are given that:
f(x) = 3x^2 - 1
g(x) = x + 2
To find (f+g)(x), all we have to do is add the above to functions as follows:
(f+g)(x) = f(x) + g(x)
= 3x^2 - 1 + x + 2
= 3x^2 + x + 1
Hope this helps :)
