Jane = x years
Tom = x+8
*5 Years Ago
Jane= x-5
Tom= (x+8)-5=>x+3---------------------------
x+3=3(x-5)<span>x+3=3x-15
3x-x=18
2x=18
x=9
Jane = 9 years
Tome = 9+8 = 17 years</span>
Step-by-step explanation:
In ascending order
100 , 102 , 103 , 106, 109
No of data (N) = 5
Now
Position of median
= ( N + 1) /2 th item
=( 5+1 )/2 th item
= 6 / 2 th item
= 3rd item
Therefore exact median = 103
Hope it will help you :)
Hi there!
The word "of" is the same thing as a multiplication sign.
1)
20% = 0.2
0.2 × 20 = 4
2)
? × 30 = 15
divide each side of the equation by 30
? = 0.5
0.5 = 50%
3)
50% = 0.5
0.5 × ? = 50
divide each side of the equation by 0.5
? = 100
There you go! I really hope this helped, if there's anything just let me know! :)
