20°
Step-by-step explanation:
ok so if 40 degrees is on one side its also on the side parallel from it
a straight line = 180 degrees
so 180 - 40 = 140
so 7x =140
we now divide 7 on both sides and get x=20 because the 7 cancels out
180 -40 =140
7x = 140
7x/7 =140/7
x=20
Hope I helped?

The answer to your question is letter D (0.6, 1.9)
Step-by-step explanation:
The solution of a system of equations is the point where the equations cross. That means that the value of x and the value of y in both equations is the same.
In the table we observe that the value "y" in both equations is closer is when x = 0.6 and y = 1.8 for one equation and 2 for the other one.
From the options given, the most approximate to this is letter D.
