List 5 numbers with a mean of 5

2 answers:

7 0

One way is to make 5 the 3rd number in a series of equally spaced numbers:

3,4,5,6,7 = mean of 5

1, 3, 5, 7, 9 = mean of five

4, 4.5, 5, 5.5, 6 = mean of five

4.8, 4.9, 5.0, 5.1, 5.2 = mean of five
Do you get the idea?

If their mean is 5, then the numbers add up to 25.
Here are a few sets that do the job:

1, 2, 3, 4, 15

10, 20, 30, 40, -75

+2, -2, +99, -99, 25

1, 5, 5, 5, 9

The length of one side of a triangular lot is 6 m less than 3 times the length of the second side. The third side is 8 m longer

Tanya [424]

second side = x

first side = 3x - 6

third side = (3x - 6) + 8

The perimeter = 80m and is equal x + (3x - 6) + [(3x - 6) + 8]

x + 3x - 6 + 3x - 6 + 8 = 80

7x - 4 = 80 |+4

7x = 84 |:7

x = 12 m

3x - 6 = 3(12) - 6 = 30 m

(3x - 6) + 8 = 3x + 2 = 3(12) + 2 = 38 m

Answer: 12m, 30m, 38m
