So if point W is somewhere on the line segment UV, then the equation UV = UW + WV is true.
![UV = UW + WV\\(13)=(2y-9)+(y-5)\\13=2y-9+y-5\\13=(2y+y)+[(-9)+(-5)]\\13=3y-14\\27=3y\\\\y=9](https://tex.z-dn.net/?f=UV%20%3D%20UW%20%2B%20WV%5C%5C%2813%29%3D%282y-9%29%2B%28y-5%29%5C%5C13%3D2y-9%2By-5%5C%5C13%3D%282y%2By%29%2B%5B%28-9%29%2B%28-5%29%5D%5C%5C13%3D3y-14%5C%5C27%3D3y%5C%5C%5C%5Cy%3D9)
Answer:
Sarah bought 2 coach tickets and 3 first class tickets.
Step-by-step explanation:
Let c and f represent the numbers of coach and first class tickets purchased. Then c + f = 5, so that c = 5 - f.
The pricing equation is therefore
$380c + $1080f = $4000. Subbing 5 - f for c, we get the revised equation
380(5 - f) + 1080f = 4000.
After simplification, this becomes:
-380f + 1080f = 2100, or
700f = 2100.
Then f = 3 and c = 5 - f = 5 - 3 = 2.

Answer:
Part A) 700 Snack Bags
Part B) [$]1225.00
Step-by-step explanation:
Pretzels and cheese puffs make up 30% (0.30) of the sales which means 210 is 30% of the total bags they sold. You could set up a ratio like this where 1 represents 100%:
210/.30 = x/1
If solved out, you find there are 700 bags total and you can check it by finding that 210 is 30% of 700.
That can also be written as 1/6y^5
