Answer: 94.5
Step-by-step explanation:
If average of 9 students is 94, their total will be 94x 9 = 846
If the 10th student scores 99, the new total is 846 + 99 = 945
So, the new average will be
945/10 = 94.5
You do 9+3 which equals 12 then you multiply that by 4
Answer:
6+2+3+3+3+5=22 is a correct answer
It would be: k+3 = 10
subtracting 3 from both sides,
k+3-3 = 10-3
k=7
