Each day, lourdes reads 30 pages of a 450-page book. write a linear equation to represent the number of pages lourdes has left to read after x days.

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

Lourdes has left to read after x days

Step-by-step 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

Step-by-step 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,

Hence a linear equation to represent the number of pages Lourdes has left to read after x days is

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
