Answer:
The equation is 216/20= 10.8 so about 11 dollars each
Step-by-step explanation:
Part B 216/ 15= 14.40 14.4 and 10.8 both round down so this awnser is reasonable
10 probably i’m not sure i’m just guessing

Why dividing by is not reliable
The reason is that, the given expression is a quadratic equation and as such, it will most likely have two solutions.
So, when the expression is divided by , the solution will be , leaving out the other possible solution.
The right way is:
Subtract 6x from both sides
Factorize
Split
Solve for x in both cases:
Answer:
x=4
y=-1
Step-by-step explanation:
x + 2y = 2
-x + y = -5
3y = -3
y = -1
If you would then plug in -1 (for y) then you would get x=4
For example:
x + 2(-1) = 2
x - 2 = 2
x = 4
OR
-x - 1 = -5
-1 + 5 = x
4 = x
x = 4
No, it doesn't. A function cannot have two x-values repeat, and this table has 2 multiple times. The answer is C.
Hope this helped!
