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)
$119 - $68 = $51
51/68 x 100 = .75
.75 x 100 = 75%
So, there was a 75% percent increase in the price.
Answer:
3 Cupcakes
Step-by-step explanation:
First, multiply the percentage, 30, times the number of cupcakes, 10, ad you get 300. Then, divide that by 100, and oyu get your answer, 3 cupcakes.
*Or since this form of equation is in a simpler form of 10 cupcakes, just get rid of the percentage sign and the 0 in 30%. I hope this helps :)
Answer:
B, C
Step-by-step explanation:
Since y=0, you are looking for equations such that 10 times the coefficient of x is the constant in the equation.
a) 5·10 ≠ 15
b) 2·10 = 20 . . . . select this one
c) 10 = 10 . . . . select this one
d) 3·10 ≠ 13
e) 4·10 ≠ 20
f) 6·10 ≠ 50
7.1(10) = 71 <== 10 times greater means multiply
