Step-by-step explanation:
We are given the following data:
Tom's Age: 10 11 12 a
Kim's Age: 13 14 15
We have to evaluate Kim's age when Tom's age is a.

After 10 weeks, the boys will have same amount in savings.
Step-by-step explanation:
Given,
Roberto already have $30.
Amount saved each week = $5
Let,
x be the number of weeks.
R(x) = 30+5x
Amount saved by Jack each week = $8
J(x) = 8x
For same amount, the functions will be equal.
R(x) = J(x)
Dividing both sides by 3
After 10 weeks, the boys will have same amount in savings.

Answer:
The value of x would be 16.
Step-by-step explanation:
In a data,
Median : middle value of the data when the data is written is ascending order.
While,
Here, the given data is,
4, 5, 6, 8, 10, and x
So, median = = = 7.
Number of the observations = 6,
Sum of the observations = 4+ 5+6+8+10+x = 33 + x
Thus,
Average =
According to the question,
Therefore, the value of x would be 16.
