To find the number of days it took Kim to read Part 1 of the book, we can solve the equation 380 - 20d = 160.
Subtracting 160 from both sides of the equation, we get:
380 - 160 = 20d
220 = 20d
Dividing both sides of the equation by 20, we get:
d = 11
Therefore, it took Kim 11 days to read Part 1 of the book.
To find the number of days it took Kim to read Part 1 of the book, we need to solve the equation:
380 - 20d = 160
First, subtract 160 from both sides of the equation:
380 - 160 = 20d
220 = 20d
Next, divide both sides of the equation by 20:
220/20 = d
This simplifies to:
11 = d
Therefore, it took Kim 11 days to read Part 1 of the book.
To find the number of days it took Kim to read Part 1 of the book, we can solve the equation 380−20𝑑=160.
To solve the equation, we first need to isolate the variable 𝑑.
Subtracting 160 from both sides of the equation gives us:
380 − 160 = 20𝑑
220 = 20𝑑
To isolate 𝑑, we divide both sides of the equation by 20:
𝑑 = 220 / 20
𝑑 = 11
So, it took Kim 11 days to read Part 1 of the book. Therefore, the answer is 11 days.
