Certainly! Let's go through the problem step-by-step.
1. Understanding the problem:
- Ivan initially had [tex]\( d \)[/tex] dollars.
- Ivan lost twenty dollars.
We need to write an expression to model this situation and then evaluate it when [tex]\( d = 35 \)[/tex].
2. Writing the expression:
- Ivan loses twenty dollars from his initial amount [tex]\( d \)[/tex].
- We can represent this situation with the expression [tex]\( d - 20 \)[/tex].
So, the expression to model the situation is [tex]\( d - 20 \)[/tex].
3. Evaluating the expression:
- We are given [tex]\( d = 35 \)[/tex].
- Substituting [tex]\( d \)[/tex] with 35 in the expression [tex]\( d - 20 \)[/tex], we get:
[tex]\[ 35 - 20 \][/tex]
- Performing the subtraction:
[tex]\[ 35 - 20 = 15 \][/tex]
So, the value of the expression when [tex]\( d = 35 \)[/tex] is 15.
Statements completion:
1. The expression to model the situation is [tex]\( d - 20 \)[/tex].
2. The value of the expression when [tex]\( d = 35 \)[/tex] is 15.
