Answer:
the difference of the product of 3x and 4 and of the sum of -1 and 2
To find the exterior angle measure we would use the following formula:

A regular hexagon has 6 sides so we divide:
360/6 which equals 60
So our final answer would be A. 60
2t + 5b = 20
8t + 3b = 29
Multiply the first equation by-4
-8t -20b = -80
8t + 3b = 29
-17b = -51
b = 3
Plug 3 in for b into either equation and solve for t.
2t + 5(3) = 20
2t + 15 = 20
2t = 5
Divide both sides by 2
t = 2.50
