7x + 18 = 8x
8x-7x = 18
x = 18
3y = 2x
3y = 2(18)
3y = 36
y = 12

Answer:
S = 4.5π ≈ 14.14 units
Step-by-step explanation:
The arc length is given by ...
s = rθ . . . . . r = radius; θ = central angle in radians
The angle 135° is ...
135° = 135°(π/180°) = 3π/4 radians
The arc of interest has length ...
s = 6×3π/4 = 9/2π ≈ 14.14 . . . units
Seven tenths of an inch would be 7/10
