X is equal to 23
15/3 = 5
36/3 = 12
39/3 = 13 then add the 10 and you get 23
Ratio: 3:4
so divide 12 by 3=4
and multiply 4 by 4=16
your friend sells 16 tickets
ratio is now 12:16
The solution to the equation one-third (x + 9) = negative 12 is x = -45
<h3>How to solve the equation?</h3>
The equation is given as:
one-third (x + 9) = negative 12
Rewrite properly as:
1/3 (x + 9) = -12
Multiply both sides by 3
x + 9 = -36
Subtract 9 from both sides
x = -45
Hence, the solution to the equation one-third (x + 9) = negative 12 is x = -45

Answer:
<h2><u>
A</u></h2>
Step-by-step explanation:
<h2>
You are going 2 up because it says plus 2 so A.</h2>
When you "combine like terms", you are putting together terms that look similar. For example, 4n and n look similar, because they both have an "n". Imagine the n's are apples, and numbers without 'n' are oranges.
If you have 4 apples, and add 1 apple, you have 5 apples, or 5n.
If you have 6 oranges, and take away 2, you have 4 oranges. But, you can't put apples and oranges together, they are 2 different fruits.
So, you're left with 5n+4!
