Answer:

Step-by-step explanation:

Solve the equation for x:

3(x + 5) = -4x + 8

Distribute.

3x + 15 = -4x + 8

Combine like terms.

3x + 15 = -4x + 8

+4x +4x

7x + 15 = 8

-15 -15

7x = -7

Divide both sides by 7.

x = -1

The following equation has one solution, x = -1.

Answer:

It will take him 20 days to read a 300-page book.

Step-by-step explanation:

Given:

Stephen read a 90-page book in 6 days.

If he continues reading at that rate.

Now, to find the time it will take him to read a 300-page book.

So, we solve using unitary method:

If, Stephen read 90 pages in 6 days.

So, Stephen read 1 page in = $\frac{6}{90}$ days.

Thus, Stephen read 300 page in = $\frac{6}{90} \times 300$

$=\frac{1800}{90}$

$=20\ days.$

Therefore, it will take him 20 days to read a 300-page book.
