When you're talking about sums, that means you are adding. So, you do 8+7=15. The sum of it being doubled, you say? 15x2=30, or 15+15=30. Hope this helped :)
Answer: draw a seconded line using a straightedge so that it intersects the first

Answer:
10(32 - n)
Step-by-step explanation:
This is a beginning algebra question. It is trying to find out if you know what a difference is.
A difference always means subtract in math. Always. There are no exceptions.
So the difference between 32 and n is 32 - n
This difference is multiplied by 10
10(32 - n)
Usually the number mentioned first is the number put to the left of the subtract sign.
If you tell me the answer is 10(n - 32) then you should say that it is the difference between n and 32.
The answer is C. The graph does not show a proportional relationship because each point written as a ratio gives a different value.
Hope this helped! If it didn't please tell me what went wrong so I can fix it.
