Question

find the mean of 3, 4, 7, 11,15
.
and one more
x/6 - 1 = 5

thanks so much

Answer 1

Mean = average = sum of all the numbers / count
(3+4+7+11+15 )/ 5= 40/5 = 8

x/6 - 1 = 5, so x/6 - 1 +1 = 5 + 1 (add +1 to both sides)
x/6 =6
x/6 * 6 = 6 * 6 (multiply both sides by 6 to get rid of the denominator)
x = 36

Answer 2

The mean is the sum of all the numbers divided by the number of numbers: (3+4+7+11+15)/5 = 8

x/6 -1 = 5
x/6 = 5 +1 = 6
x = 36

Answer 3

mean = sum of the numbers/total no. of numbers
sum = 3+4+7+11+15 = 40
no. of nos. = 5
mean = 8
x/6 - 1 = 5
x/6 = 5+1 = 6
x = 36

Answer 4

add all the number and divided by how many number there are.

(3+4+7+11+15) / 5 = 8

x/6-1=5
x/6=6
x=36

Answer 5

mean of 3,4,7,11,15

3+4+7+11+15=40

40/5=8

8 is the mean.

x/6-1=5

x/6=6

x times 6=6 times 6

x=36

Answer 6

3 + 4 + 7 + 11 + 15 = 40

40 / 5 = 8

The mean is 8

- - - - - - -

x/6 - 1 = 5

6(x / 6 ) - 6(1) = 6(5)

x - 6 = 30

x - 6 + 6 = 30 + 6

x = 36

- - - - - -s-

Answer 7

add all the number and divided by how many number there are so the mean of 3,4,7,11,15 is
8.

and the other one is 36

36/6 = 6 -1 = 5.
x=36

Good Luck!! :)

Answer 8

hi chum this an common question in keeping with linear equations you need to use transposition technique throughout the time of this equipment whilst a term is transfered from one element to different its sign turns into opposite answer: x+4-7x=22 =4-7x=22-x (right here x comes from the left element its sign variations) =4=22-x+7x(right here 7x comes from the left element its sign variations) =4-22=6x(same) =-18=6x x=-18/6 =-3 Bye Bye!!!!!!!!!!!!!!!!!!!!!!

Answer 9

8

x=36
