Exercise 6 Page 8

Write an equation to solve for the unknown value.

26 inches

Practice makes perfect

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.

60 = 5k - 70
60 + 70 = 5k - 70 + 70
130 = 5k
130/5= 5k/5
26 = k
k = 26

Therefore, the height of the kakapo is 26 inches.
