Answer:
a = 1/5 b
Step-by-step explanation:
A direct variation is given by
a = k*b where k is the constant of variation
3 = k* 15
Divide each side by 15
3/15 = k*15/15
1/5 = k
Answer: m = 5/2
..............................
209,000
(500+200=700)
(700*300=210000)
210000-1000=209,000
13, 11
common difference=-2
15+(-2)=13
13+(-2)=11
x=3 and x=5
its half of the bottom number
