If the first chapter of a certain book is 28 pages long and makes up 4% of the book, how many pages does the entire book have?

Schach [20]

Answer:

700 pages

Step-by-step explanation:

I first found out how many pages were in 1% so I divided 28 by 4.

I got 7 so I multiplied it by 100 and 700 was the answer.

Basically:

28÷4 = 7

7 x 100 = 700

I hope that kinda made sense!

Please help me this question

Annette [7]

Step-by-step explanation:

Hey there!

The given point is (8,-3) as (x1,y1) and slope (m) = -3/4.

Note: use one point formula for finding the equation.

$(y - y1) = m(x - x1)$

Put all values.

$(y + 3) = - \frac{ 3}{4} (x - 8)$

Simplify it.

$(y + 3) = - \frac{ 3}{4} x - 8 \times - \frac{3}{4}$

$(y + 3) = - \frac{3}{4} x + 6$

$y = - \frac{3}{4} x + 6 - 3$

$y = - \frac{3}{4} x + 3$

Therefore, the equation is; y = -3/4x+3.

Hope it helps...
