17. HUMAN HEIGHT Micah's adult height is one less than twice his height at age 2.
Micah's adult height is 71 inches. Write and solve an equation to find Micah's
height h at age 2.

Answer 1

Explanation:

Let "H" equal Micah's adult height and "h" equal his height at age 2.

`H=2h-1`

`H=71`

`71=2h-1\\71+1=2h-1+1\\72=2h\\(72)/(2)=(2h)/(2)\\36=h`

Therefore, Micah's height "h" at age 2 is 36 inches.

Answer 2

Answer: 36 inches

Explanation:

Let Micah's height at age 2 be 'x'.

Given : Micah's adult height is one less than twice his height at age 2.

i.e. Micah's adult height =
`2h-1`

Also, Micah's adult height is 71 inches.

According to the question, we have

`2h-1=71\\\\\Rightarrow\ 2h=71+1\\\\\Rightarrow\ 2h=72`

Divide 2 from both the sides , we get

`h=36`

Hence, Micah's height at age 2 = 36 inches
