To determine the predicted height of the plant 5 days from today using the expression \( 1.5t + 20 \), we can follow these steps:
1. Identify the expression and the variable:
- The expression given to predict the plant's height is \( 1.5t + 20 \), where \( t \) represents the number of days from today.
2. Substitute the value of \( t \) with the given number of days:
- We need to find the height of the plant 5 days from today. Hence, \( t = 5 \).
3. Substitute \( t \) with 5 in the expression:
[tex]\[
1.5(5) + 20
\][/tex]
4. Calculate the multiplication first:
[tex]\[
1.5 \times 5 = 7.5
\][/tex]
5. Add the constant value to the result of the multiplication:
[tex]\[
7.5 + 20 = 27.5
\][/tex]
6. State the final result:
- The predicted height of the plant 5 days from today is \( 27.5 \) centimeters.
Therefore, the predicted height of the plant 5 days from today is 27.5 centimeters.
