Kellie's original number given the analogy and corresponding equation is 13
<h3>How to write and solve equation?</h3>
let
(x × 2) × 3 = x + 65
2x × 3 = 65 + x
6x = 65 + x
6x - x = 65
5x = 65
x = 65/5
x = 13
check:
6x = 65 + x
6(13) = 65 + 13
78 = 78
Therefore, the unknown number, x is 13

1. Since 9 pages in 3 hours were read, we would find the greatest common factor (GCF) of both numbers, which is 3. So you do 9 divided by 3 (3) and 3 divided by 3 (1) which leaves you with the unit rate 3/1 or 3 pgs. p/ hr.
2. 20/4. The GCF of 20 and 4 is 4. So 20 divided by 4 is 5 and 4 divided by 4 is 1. Therefore leaving you with the unit rate 5/1 or 5 lb. p/ $.
3. 60/2. The GCF of 60 and 2 is 2. 60 divided by 2 is 30. 2 divided by 2 is 1. So the manatee can surface again in 30 seconds. 30/1 or 30 b. p/ sec.
