Answer: Yes!
Step-by-step explanation:
If the x and y coordinates form proportional relationships, then there is some non-changing number (a constant) that when multiplied times x will create y. In this example, that number is 3 (y = 3x), and is called the constant of proportionality. ... It is a positive number.
Answer: 
Step-by-step explanation:
Solve for the first variable in one of the equations, then substitute the result into the other equation.
Add the equations in order to solve for the first variable. Plug this value into the other equations in order to solve for the remaining variables.

You cannot tell which number is greater just by the leftmost digits. This is because you do not know how many digits each number has. Ex: 80 and 3,000
Answer:
I might be in highschool, but I'm sure I can still help.
Step-by-step explanation:
See the 45 degree angles? that means they're equal sides. So 4v2 = 5.65, right? so if you take 180 - 5.65, and then divide by two, you should have the length to each of those sides. They're equal, remember. So, the answer would be 180 - 5.65 = 174.35. 174.35 / 2 = 87.175. In this case, k = 87.175 :)
