Answer:
Step-by-step explanation:
1) 4(2a+p)=c+p+a
2) Expand: 8a+4p=c+p+a
3) subract a and 4p: 7a=c-3p
4) Divide: a=
350 - 213 - 155 + 78 = 60 students not in either
Answer:
The question is pretty vague, but I think I know what you are asking.
Step-by-step explanation:
The question states clearly the amount of dice picked that is not black.
Therefore, the equation is as so:
Total amount of dice - Total amount that is black
/
Total amount of dice
Or
10 non-black dice/
15 total dice
4x➕6(503-x)=2296
Distribute the 6 into the parentheses
Let x represent the students
503-x will represent the non-students
4x➕3018➖6x=2296
Then combine like terms
-2x➕3018=2296
Now since you move your constant your sign has to change as well,
-2x=2296➖3018
Then subtract
-2x=-722
Then divide both sides by -2
You are left with x=361
This represents the students
503➖361= 142 which equal the non-students
Therefore your answer is:
361=students
142=non-students
Hope this helps! :3
