Answer:

Step-by-step explanation:
The general direct variation equation is
y = kx
Plug in x = 4 and y = 6 and solve for k.
6 = k * 4
4k = 6
k = 6/4 = 3/2

Multiple 11/25 with 4 and 9/20 with 5 so it will be
44/100 and 45/100
Answer:
H) B= 13
Step-by-step explanation:
<em>5 + b = 18</em>
<em>F) 5 + 5 = 10 so not equal to 18. It is not a solution</em>
<em>H) 5 + 13 = 18 it's equal . so it is the solution</em>
<em>G) 5 + 8 = 13 so not equal to 18. It is not a solution</em>
<em>J) 5 + 23 = 28 so not equal to 18. It is not a solution</em>
