Answer:

6 packs, 9 packs

Step-by-step explanation:

The ratio of mechanical pencil to free eraser is <em>2:4, or 1:2</em>.

So that means, for every free eraser you get, you bought the double amount of pencils.

12 free erasers x 2 = <em>24 pencils</em>

18 free erasers x 2 = <em>36 pencils</em>

And a pack of pencils contains 4.

24/4 = 6 packs

36/4 = 9 packs

8/3 x 9/7 or 8/3 x 9/4<br> Which is greater? How do you know?
Vinvika [58]

Well, let's multiply them!

8/3 * 9/7 = 72/21

8/3 x 9/4 = 72/12.

We know the one with the smallest denominator is larger if the numerator is the same. So that means

72/12 is larger.

9. What is the slope of the line through the points (-2, -1) and (4, 3)?
Fofino [41]

Step-by-step explanation:

given points,

(-2, -1) and (4,3)

we know,

slope of line = y_2 - y_1/ x_2 - x_1

x_1 and y_1 = -2 , -1

x_2 and y_2 = 4 , 3

according to the formula

3 - (-1)/4 - (-2)

→ 3 + 1/4 + 2

→ 4/6

→ 2/3

or (2,3)

therefore, slope of the given line is (2,3).

Hope this answer helps you dear!
