Answer:
B. (-3, -7)
Step-by-step explanation:
Anytime you rotate a number 180° about the origin, the numbers in the coordinates become their opposites.
-3 is the opposite of 3 and -7 is the opposite of 7.
Therefore, your new coordinates are (-3, -7)
(x,y) becomes (-x,-y)

Answer: x-3, 3, is not equal to
Step-by-step explanation:
Nearest 10 is according to the last digit.
if the digit is >5, it +1 to the tenth digit. If it's <5, it will be reduced to 0.
for your case, 392, 2 < 5, therefore rounded up to nearest tenth is 390.
Answer:
Equation C: 5/8x + 2..5 = 3/8x + 1.5 + 1/4x
Step-by-step explanation:
Let us go through each of the equations one by one.
Equation A: 
This simplifies to
which has infinitely many solutions.
Equation B: 
this simplifies to
which is exactly one solution.
Equation C: 
this simplifies to
There's no way this is going to be possible; this equation has no solutions.
Equation D: 
this gives
which is exactly one solution.
Thus we see that it is equation C that has no solutions.
