187 ft/s. I think that this might be an equation, but if it is not, I'm sorry.

when ashley buys 7 postage stamp booklets she gets 140 stamps.she get 60 stamps in three booklets. write an equation to find the

Andreyy89

We can put this information into two equations:

7 booklets = 140 stamps
3 booklets = 60 stamps

Let us then focus on one equation to find the relationship:

7 booklets = 140 stamps

If we put that into a fraction, we get $\frac{7}{140}$ or $\frac{1}{20}$ .

This means that for every booklet, Ashley gets 20 stamps; or rather, each booklet has 20 stamps.

We can then see that this relationship holds true for the second equation as well:

$\frac{3}{60}$ or $\frac{1}{20}$ .

To write a general equation for this relationship using p for the number of postage stamps, and b for the number of booklets:

p = 20b

Where b is equal to p.

Find the other endpoint of the line segment with the given endpoint and midpoint.

Shtirlitz [24]

Answer:

endpoint is (29, -13)

Step-by-step explanation:

Formula for midpoint is $(\frac{x_{1} + x_{2} }{2} ,\frac{y_{1} + y_{2} }{2} )$

So, let $(x_{2} , y_{2} )$ be the coordinates of the endpoint you are looking for.

$x_{1} = -9$ and $y_{1} = 7$

$(\frac{-9 + x_{2} }{2} , \frac{7 + y_{2} }{2} )$ = (10, -3)

$\frac{-9 + x_{2} }{2} = 10$ $\frac{7 + y_{2} }{2} = -3$

-9 + $x_{2}$ = 20 7 + $y_{2} = -6$

$x_{2} = 29$ $y_{2} = -13$

endpoint is (29, -13)

Whic one is further from zero -3 or -2

Bond [772]

-3 is further away from 0 because if you graph it on a number line, it will show that -3 is one unit further from 0 than -2.
