3x=8
Solve for x by dividing by 3 on both sides
x=8/3
Now plug 8/3 in for x in second equation
3(8/3)+y=15
This gives you
8+y=15
Subtract by 8 on both sides to find y
y=8
Now write it in ordered pair form (x,y)
So your answer is (8/3,8)
y=12-1.25x
honestly i dont know if this is right so sorry if its not.
no it cannot.

Answer: 25y/2x
Explanation:
First you need to find the GCF of 125 and 10, which is 5
making it 25y^2/2xy, Then you get rid of 1 of the y's from both of the sides because you don't need them, they cancel eachother out, 25y/2x
I hope this helped!

Answer:
The octagon is regular, all of its sides and angles are congruent. Thus, the measure of each angle is equal to the sum of its angles divided by 8. Therefore, each angle in the polygon has a measure of 1080/8 =135 degrees.
