Answer 1

Let \( x \) represent the number of weekdays Lindsay practiced.

From the problem, we know the following:

• Lindsay practices 50 minutes on Saturday.
• Lindsay practices 30 minutes on each weekday.

Given that she practiced a total of 140 minutes last week, we can set up an equation. The total practice time can be represented as the sum of the minutes she practiced on Saturday and the minutes she practiced on weekdays.

The equation can be written as:

\[ 30x + 50 = 140 \]

In this equation:

• \( 30x \) represents the total minutes practiced on weekdays (30 minutes each day for \( x \) weekdays),
• \( 50 \) represents the minutes practiced on Saturday,
• \( 140 \) is the total minutes practiced last week.

So, the final equation is:

\[ 30x + 50 = 140 \]
