13.5 because 4.5 times 3 is 13.5
Answer:
angle Y = 90 degrees
Step-by-step explanation:
Since it is stated that angle x forms a straight line with the 50 and 50 degree angles, and that angle x is vertical to angle y, we can do 40+50+y=180 to find angle Y.
I believe the answer is A! If not I’m so sorry but I hope you pass!
![5 - 6 = - 3k \\ - 1 = - 3k \\ \frac{1}{3} = k](https://tex.z-dn.net/?f=5%20-%206%20%3D%20%20-%203k%20%5C%5C%20%20-%201%20%3D%20%20-%203k%20%5C%5C%20%20%5Cfrac%7B1%7D%7B3%7D%20%20%3D%20k)
First, we combine the terms on the left side of the equation to simplify the equation. Then we divide both sides by -3. k then equals 1/3.
To check, we plug in our value for k into the original equation:
![5 - 6 = - 3k \\ 5 - 6 = - 3( \frac{1}{3} ) \\ - 1 = - 1](https://tex.z-dn.net/?f=5%20-%206%20%3D%20%20-%203k%20%5C%5C%205%20-%206%20%3D%20%20-%203%28%20%5Cfrac%7B1%7D%7B3%7D%20%29%20%5C%5C%20%20-%201%20%3D%20%20-%201)
We found k to be 1/3, so for every instance of k, we plug in 1/3. To simplify, we combine the left side to get -1, and we combine the right side to get -1.
Since -1 = -1, our solution is correct.
