This one is a bit confusing without a diagram anyway. We'll assume the typical labeling where A and B are consecutive angles, so the transverse line AB through the parallels makes A and B supplementary:
A + B = 180 degrees
12x + 46 + 7x + 1 = 180
19x = 180 - 47 = 133
x = 133/19 - 7
Answer:
X = 0.8
Step-by-step explanation:
reorder the terms by moving all terms that contain X to the left, and all the others to the right.
add 2X to both sides
Combine like terms
add (-5) to both sides
combine like terms
divide both sides by 5
The answer to your question is A. Y= -4x-9 because is you look at the pre written equation it shows that 4x is negative and that 9 is negative too. Also, if you rewrite an equation you have to isolate Y. Therefore A is the correct answer
Answer:
SY = 16
XY = 12
Step-by-step explanation:
15/20 = 12/SY
15SY = 240
SY = 16
15/20 = 9/XY
15XY = 180
XY = 12
