A knitter with 14 skeins of yarn can make 7 scarves

Explanation:
We can use a proportion to solve this

4 skeins of yarn
-----------------------
2 scarves

That is the information we know. What we want to do is find out how many scarves for 14 skeins of yarn, like this

4 14
-- = ---
2 ?

To get from 4 to 14, you multiply by 3.5. We must to the same thing to the bottom as well. So we multiply 2 by 3.5, which gives us 7

x3.5
4 14
-- = ---
2 7
x3.5

If lines L and M are parallel, find x, y, and z. Explain your reasoning.
Katyanochek1 [597]

Answer:

The answer to your question is:

                                                     x = 43°, y = 137° and z= 43°

Step-by-step explanation:

-If lines L and M are parallel, that means that 43° and z are corresponding angles and they measure the same.

                                           z = 43°

- y and 43° are supplementary angles , so

                                          y + 43 = 180

                                          y = 180 - 43

                                          y = 137°

- x and z are vertical angles, so they measure the same

                                          x = z = 43°
