The answer to this question is A - 56.5.
Angles 6 and 1 are both on a 180 degree line. When we subtract the measurement of 6 from 180 degrees, we can get the measurement for angle 1.
Answer:
Step-by-step explanation:
A 180 degree rotation around the origin would be the same things as a reflection across the x-axis followed by a reflection across the y-axis.
This would result in the new location being (-3, -2) The x coordinate is -3.

Answer:
5.714 liters of the 5% solution and 4.286 of the 40%.
Step-by-step explanation:
Let x be the volume of 40% solution and y = volume of the 5% solution.
x + y = 10
0.40x + 0.05y = 0.20(x + y)
From the first equation x = 10 -y so we have:
0.40(10 - y) + 0.05y = 0.20( 10 - y + y)
4 - 0.40y + 0.05y = 2
-0.35y = -2
y = 5.714 liters of the 5%.
and x = 10 - 5.714 = 4.286 liters of the 40% solution.
