Answer:
x = 6 y = -9
Step-by-step explanation:
8x +2y = 30
-7x + 2y =24
x= 6
8(6)
48 + 2y =30
-48. -48
2y = -18
÷2. ÷2
y = -9
Answer:
i am sorry i don't know the answer
i love you
Step-by-step explanation:
Answer:
It's the first choice (20 degrees).
Step-by-step explanation:
These angles will be equal ( by The Alternate Angle Theorem).
5(x - 2) = x + 14
5x - 10 = x + 14
4x = 24
x = 6.
So the measure of each angle = 5(6 - 2) = 6 + 14 = 20 degrees.

M is the
midpoint of CD. Given
-------------------------------------------------
Both ends of the
line segment to
M is equal. Definition of midpoint
-------------------------------------------------
CM = 5x-2 and
MD = 3x+2. Given
-------------------------------------------------
CM = MD. As above, definition
of midpoint
-------------------------------------------------
5x-2 = 3x+2. Substitution
-------------------------------------------------
5x-3x = 2+2
2x = 4 Rules of Algebra
x = 2
