You are told the ages of Karen and David in terms of Michelle's age.
Let m = Michelle's age.
Michelle's age = m
Karen's age = m + 6
Michelle is two years younger than David, so David is two years older than Michelle.
David's age = m + 2
Add the ages and get 62.
m + m + 6 + m + 2 = 62
3m + 8 = 62
3m = 54
m = 18
Michelle is 18 years old
Karen is 6 years older, so she is 24 years old.
David is 2 years older than Michelle, so he is 20 years old.
Answer:

Step-by-step explanation:
Given that t and w vary inversely then the equation relating them is
t = 
← k is the constant of variation
To find k use the condition t = 
when w = 4
k = tw = × 4 = 
t = 
← equation of variation
When w = 9, then
t = 
= 
Answer:
The answer is 3 3/10
Step-by-step explanation:
2 + 1/2 + 4/5
= 2 + 5/10 + 8/10
= 2 + 13/10
=2 + 1 3/10
= 3 3/10

Answer:
Associative Property
For multiplication, the rule is "a(bc) = (ab)c"; in numbers, this means 2(3×4) = (2×3)4.
