Each time the previous number is multiplied by 2
Answer:
Adding 12 to the circle area is equal to the square area.
Or
s2 = 12 + A
Where
s = side of square
A = area of circle
So
s2 = 12 + 36
s2 = 48
Solve this for s to get the side length
Answer:
Mean: 50.8 or 51 (rounded)
Median: 51.5 or 52 (rounded)
Step-by-step explanation:
To find the mean I added all the numbers then divides my sum but the number of numbers.
To find the median I listed the numbers from least to greatest.There are two middle numbers so I added the two numbers and divided the same by 2.
Answer: x = 23 and y = 13
Explanation:
let x and y be the two number.
Where:
(x + y)/2 = 18 => x + y = 18 x 2 = 36
and:
x - y = 10
Thus we get:
x + y = 36 (1)
x - y = 10 (2)
Add (1) and (2):
x + y + x - y = 36 + 10
2x = 46
x = 23
If x = 23
then x - y = 10
23 - y = 10
-y = -13
y = 13
