Answer:
12
Step-by-step explanation:
10x-11+3x-2+3x+1=180
16x-12=180
16x=192
x=12

Answer:
Let X be the number of weeks.
2x - 16 = 14
we add 16 on both sides.
2x = 30
now we divide 2 on both sides to get rid of the 2 to the x, we want to get x on its own.
X = 15
Y=kx+b
2k+b=-1
6k+b=1
6k+b-2k-b=2
4k=2
k=1/2
b=-2
y=1/2x-2
So your answer is option A

Answer:
20.25 mm
Step-by-step explanation:
Arc length is given by the relation ...
s = rθ
where r is the radius and θ is the central angle in radians.
There are π radians in 180°, so the arc length is ...
s = (5 mm)(232°×π/180°) = 20.25 mm
The arc length is about 20.25 mm.
