Answer:


y=450-30x

Explanation:

She reads pages in 1 day = 30

Lourdes has left to read after x days.

She read pages in x days = 30 x

Total pages = 450

Pages left = 450-30x

Let y be the pages left

So,
y=450-30x

Hence a linear equation to represent the number of pages Lourdes has left to read after x days is
y=450-30x

Answer:

The linear equation is y = 450 - 30 x, where y is the number of pages

Lourdes has left to read after x days

Explanation:

- Each day, Lourdes reads 30 pages of a 450-page book

- We need to write a linear equation to represent the number of pages

Lourdes has left to read after x days

∵ Lourdes reads 30 pages each day

∵ Lourdes will read for x days

∴ The number of pages Lourdes will read in x day = 30 x

- The left pages will be the difference between the total pages of the

book and the pages Lourdes read

∵ The book has 450 pages

∵ Loured will read 30 x in x days

∴ The number of pages left = 450 - 30 x

- Assume that y represents the number of pages Lourdes has left

to read after x days

y = 450 - 30 x

* The linear equation is y = 450 - 30 x, where y is the number of

pages Lourdes has left to read after x days
