"a ∝ b" means "a is proportional to b", which in turn means there is some constant k such that
a = kb
We're given that a = 18 and b = 3, so that
18 = 3k ⇒ k = 6
Then when b = 5, we would have
a = 6 × 5 = 30
The range would be the difference between the lowest age and the highest age.
The highest age is 76, the lowest age is 30
The range is 76 - 30 = 46
Answer:
u=18
Step-by-step explanation:
u/3 =6
Multiply each side by 3
u/3*3 =6*3
u = 18
I believe it is 8,459,999,894,000,001
