You can express this as a system of equations:

x in this instance will be her present age.

x + 8 = 2x + 3

Della by tree seedling that was 2 1/4 feet tall during the first year it grew 1 1/6 ft after two years it was 5 ft tall how much
jasenka [17]
<h2>Greetings!</h2>

Answer:

\frac{19}{12} feet

Step-by-step explanation:

First, we need to find the height after one year:

2.25 + 1 1/6 = \frac{41}{12}

Now to find the amount in the second year, we can subtract the above amount from 5:

5 - \frac{41}{12} = \frac{19}{12}

So in the second year it grew \frac{19}{12} feet


<h2>Hope this helps!</h2>
