Answer:
y=9 and x=18
Step-by-step explanation:
You know that y+3=12 so 12-3=9
You know that x-3=15 so 15+3=18
(2/3)(30)=20
30+20=50=(x/5)
(50*5)=x=250
hope this helps
Answer:
b = 5/12
Step-by-step explanation:
You have the proportion
1/(3b) = 4/5
Cross multiply to get rid of the fractions...
5 = 12b now solve for b
5/12 = b (divide by 12 on both sides)
They are not proportional
