26 inches
In this exercise, the height of a kakapo relates to the height of an emu. The height of the emu is given, and we need to use it to determine the height of the kakapo. We can rewrite the given information as algebraic expressions to create an equation for the kakapo's height.
| Given Information | Algebraic Expression |
|---|---|
| height of the kakapo | k |
| five times the height of the kakapo | 5k |
| the emu is 60 inches in height, and it is 70 inches less than five times the height of the kakapo | 60 = 5k - 70 |
Now that we have the equation, we can solve it for k, the height of the kakapo.
LHS+70=RHS+70
Add terms
.LHS /5.=.RHS /5.
Calculate quotient
Rearrange equation
Therefore, the height of the kakapo is 26 inches.
