73.
18 = 3x (divide both sides by 3 )
6 = x ( multiply both sides by
)
6 = 3x [
×
= 3 ]
divide both sides by 3
x = 2
74.
24 = 2x ( divide both sides by 2 )
12 = x ( multiply both sides by
)
12 = 2x ( divide both sides by 2 )
x = 6
75.
9 × x = 18
( divide both sides by 9
)
x = 2
76.
2 = x × ( multiply both sides by
)
2 = 4x ( divide both sides by 4 )
x =
Answer:
The values of x and y is given by the equation .
Step-by-step explanation:
Given : Five whole numbers are written in order 4 6 x y 10 , the mean and median of the five numbers are the same.
To find : The values of x and y ?
Solution :
Observations 4, 6, x, y, 10.
Mean is summation of observation divided by number of observation.
i.e.
Median is middle term of observations.
Median of odd terms term
term
The mean and median of the five numbers are the same.
i.e.
The values of x and y is given by the equation .
