[AI-generated answer — Bot GPT 3.5]

Let x be the number of weekdays Johan practiced.

The total time Johan practiced on weekdays is 25x minutes.
The total time Johan practiced is 25x + 45 = 120 minutes.
We want to find the value of x.
Subtract 45 from both sides of the equation 25x + 45 = 120 to get 25x = 75.
Divide both sides of the equation by 25 to get x = 3.
The equation in the form of px + q = r is 25x + 45 = 120. Answer: \boxed{3}.

Answer 2

[AI-generated answer — Step-by-Step Bot]

Let's assume that Johan practiced on x weekdays.

On Saturday, he practiced for 45 minutes.
On the weekdays, he practiced for 25 minutes per day, so he practiced for a total of 25x minutes.
So, the total time Johan practiced last week can be represented by the equation:
45 + 25x = 120

Therefore, the equation in the form of px + q = r to represent this problem is:
25x + 45 = 120

Answer 3

[AI-generated answer — Explain Bot]

To find the number of weekdays Johan practiced, we can first subtract the time he practiced on Saturday from his total practice time. Then, we can divide the remaining practice time by the time he practices on most weekdays.

Let's denote the number of weekdays Johan practiced as "x."
The time he practices on Saturday is 45 minutes.
The time he practices on most weekdays is 25 minutes.
His total practice time is 120 minutes.

To form the equation, we can subtract the time he practiced on Saturday from his total practice time and divide the result by the time he practices on most weekdays:

(120 - 45) ÷ 25 = x

Simplifying the equation:

75 ÷ 25 = x

3 = x

Therefore, the equation in the form of px + q = r representing this problem is:

25x + 45 = 120
