"What percent" is our unknown x, "of" means we will multiply, "is" means equals. We set up the equation accordingly: x(12.5) = 39. 12.5x = 39. Divide both sides by 12.5 to get x = 3.12. To get to the percent form we multiply by 100 to get 312%.
Adjacent angles create linear pairs so they add to 180. If we know the measure of one angle, we can find the other by subtracting from 180.
Vertical lines create congruent angles. If we know the measure of one angle, we know the measure of the angle opposite of it (they only share a vertex, no sides)

Given the concentration,
Answer:
x + z = 180
x = 180 - z
y + z +10 = 180
y = 170 - z
w + z - 13 = 180
w = 193 - z
x + y + w = 180⁰
180 - z + 170 - z + 193 - z = 180
-3z = -363
z = 121⁰
Answer:
b = (c-3a)/2
Step-by-step explanation:
3a+2b =c
Subtract 3a from each side
3a-3a+2b =c-3a
2b = c -3a
Divide each side by 2
2b/2 = (c-3a)/2
b = (c-3a)/2
