a 4 1 
b 6 1.5 
c 20 5 
d 16 4 
On what question did u go wrong
The answer is 6x, all u gotta do is add the 2 with the same variable (x)
When you multiply 5 by 1 you get 5. When you multiply 5 by 2 you get 10. If you keep doing this, you get a list of multiples of 5.
5
10
15
20
25
30
35
40
45
50
All of these numbers end in either 5 or 0. We can do the same with 2's and 10's.
2
4
6
8
10
12
14
16
18
20
For all 2's we can see that they are all even and end with an even number (0,2,4,6,8)
10
20
30
40
50
60
70
80
90
100
For 10's we can see that they all end in 0.
What is the question if it 98-49 than it would be 49
