Answer:
r = 90
Step-by-step explanation:
Our goal is always to get the variable we're trying to solve for on one side of the =, and everything else on the other side. Since we are solving for r here, we want to get rid of the 20 first, and then the 2.
subtract 20 from both sides:
divide both sides by 2:
106 people I think. because 12×n is 12n And 31×41 Is 1271 then take 12n ÷1271 Is 105.96... then rounded to the nearest person is 106
14c^2d
42c^3d
The greatest common factor of the terms 14c^2d and 42c^3d is 14c^2d~
Supplementary angle = 180 degrees
angle 1 = x
angle 2 = 3x (three times the supplementary)
3x + x = 180
4x = 180
x = 45 degrees
angle 1 = 45 degrees
angle 2 = 135 degrees
