A, B, E, and F are mathematical sentences.
An angle is the intersection of two noncollinear rays at a common endpoint. The rays are called sides and the common endpoint is called the vertex.
Answer: x= 385/12
Step-by-step explanation:
You would first change the denominator to some number that is common. Then combine the like terms. Lastly, subtract the fraction from the equal and you get your x.

Y=16/3 x -1
First, you minus both sides by 16x. This will get you -3y = 3 - 16x
Then, you divide both sides by -3. Hence on the right hand side you will get 3 - 16x over -3, which can be split into (-16x/-3) + (3/-3). By simplifying this you can get 16/3 x - 1.
The sum of two numbers is 20 and their difference is 4. Which is the greater of the two numbers? The answer is 12.
