Answer:
x equals to - 5.5 or - 11/2
Answer:
She is wrong.
Step-by-step explanation:
The mean score is
7 + 8 + 3 + 0 + 2= 20
We then divide it by the number which is 5
20/5= 4.
Therefore, Maria is wrong.
This is because she divided by 4 instead of 5, as she didn't include the rational number 0.

2=1x+3
Subtract 3 on the other side:
2-3=1x+3-3
-1=1x
Divide:

x=-1
