Okay, let's work on each sentence step by step:

1. "If you (to have) breakfast then you (not to be) hungry yesterday."
To solve this, we need to use the past simple tense.
So the correct form of the verb "to have" in the first part of the sentence would be "had".
For the second part, we need to use the negative form of the past simple, which is "were not".
Putting it all together, the sentence should be: "If you had breakfast, then you were not hungry yesterday."

2. "If I (to find) 100$ in the street, I (to keep) them."
First, we need to change the verb "to find" to its past simple form, which is "found".
Then, for the second part of the sentence, we need to change "to keep" to its past simple form, which is also "kept".
So the sentence should be: "If I found 100$ in the street, I kept them."

3. "If she (to sell) the car, she (to get) much money for it."
For the first part of this sentence, we need to change "to sell" to its past simple form, which is "sold".
The second part, "she (to get)", doesn't need any changes because "to get" is already in the correct form.
Therefore, the sentence should be: "If she sold the car, she got much money for it."

4. "I wish I (to have) a lot of experience."
This sentence is in the present unreal condition, so we need to use the past simple tense.
The correct form of the verb "to have" in the past simple is "had".
So the sentence should be: "I wish I had a lot of experience."

5. "If Bob (to learn) the rule, he (to get) a good Mark."
To solve this, we need to change "to learn" to its past simple form, which is "learned".
And for the second part, "to get" doesn't need any changes because it's already in the correct form.
So the sentence should be: "If Bob learned the rule, he got a good mark."
