The last option represents all the colours of the shirts
Answer:
The coefficient in the equation is 0.25.
It represents the rate of change (decrease factor) or the slope.
Depending on the context, it can have different representations.
The point-slope formula of a line:
Substitute:
The slope-intercept form: 
The standard form: 
Wow...we have lots of numbers to go through. we know that a 6 sided figure is a hexagon and the interior angles add up to be 720°. so.....
∠A + ∠B + ∠ C + ∠D + ∠E + ∠F = 720°
(x - 60) + (x - 40) + 130 + 120 + 110 + (x - 20) = 720
3x + 240 = 720 (combined all like terms)
3x = 480 (subtracted 240 from both sides)
x = 160 (divided both sides by 3)
put the value of x into ∠A (x - 60) = 160 - 60 = 100
∠A = 100°
