For this case we must find the current height of Osian. For this, we use the following rule of three:
1.5 m ----------------> 100%
x -----------------------> 120%
From here, we clear the value of x.
We have then:
Answer:
The current height of Osian is given by:
Using equations to solve the word problem, Katherine's age is 8 years
<h3>Word Problem</h3>
Word problem are often mathematical problem that are represented in words and sometimes can be solved using an equation.
To solve this problem, we have to represent the problem using mathematical equations;
Let;
Katherine's age = x²
Alexandra = 5(x + 1)
Sum of their age = 109
5(x + 1) + x² = 109
5x + 5 + x² = 109
x² + 5x - 104 = 0
Solving for the equation; x = 8
Katherine's age is 8
