Answer:
21
Step-by-step explanation:
65+86+104+2x+3x = 360
5x = 360-65-86-104
= 105
x =21
The values of x and y are 8 and 10, respectively
<h3>How to determine the values of x and y?</h3>
The list of the numbers is given as:
4, 7, x, y, 11
The mean and median of the five numbers are the same.
The median is the middle number.
So, we have
Median = x
This means that
Mean = Median = x
The mean is calculated as:
Mean = Sum/Count
This gives
(4+ 7+ x+ y+ 11)/5 = x
Evaluate the sum
(22 + x + y)/5 = x
This gives
22 + x + y = 5x
Evaluate the like terms
4x = 22 + y
Based on the order of the list, we have:
7 < x < y < 11
Assume y = 10
4x = 22 + 10
This gives
x = 32/4
x = 8
Recall that:
7 < x < y < 11
This means that
7 < 8 < 10 < 11
The above is true
Hence, the values of x and y are 8 and 10, respectively

M equals 56 and b equals 30
Answer:
180
Step-by-step explanation:
first you need to add ten to 80 and then it gives you 90, but tom had 100 and gave ten to Ahmad resulting in 10 more. so that means 90 x 2 = 180
The answer is =2,912
