Given:
3 kids
72 is the product of their ages.
There is a youngest child.
This means that all three are of different ages. We need to factor 72 into 3 integers.
Let us use prime factorization:
72 ÷ 2 = 36
36 ÷ 2 = 18
18 ÷ 2 = 9
9 ÷ 3 = 3
Prime factors are: 2 x 2 x 2 x 3 x 3 OR 2³ x 3²
3 ages.
eldest = 3³ = 9
middle = 2² = 4
youngest = 2¹ = 2
2 x 4 = 8
8 x 9 = 72
Answer:
y = 2/5 x - 3/5
Step-by-step explanation:
2x = 5y + 3
Rewrite
5y + 3 = 2x
Subtract 3 from both sides
5y = 2x - 3
Divide both sides by 5
y = 2/5 x - 3/5
Infinite solutions; both equations are the same.

Divide actual distance by the distance of the scale miles
39 miles / 13 miles = 3
Multiply that by the scale inches:
2 inches x 3 = 6 inches.
The answer is 6 inches.
