Answer:
C. No solution
Step-by-step explanation:
System of Equations:
A)
B)
Simplifying and rearranging equation A.
Dividing each term by 3 (common factor for each term) in equation A.
Subtracting both sides by
Adding 7 both sides.
Adding the above equation to equation B.
+
We have
which is not true.
Hence the system has no solution. (Answer)
Answer:
Angle ADC = 58 degrees
Step-by-step explanation:
Since it is a right angle...
(-6x + 2) + (-4x + 38) = 90
-10x + 40 = 90
-10x = 50
x = -5 ---- > -4(-5) + 38 ---> 20+38 ---> 58
