A circular wheel is fixed on an equilateral triangular frame as shown in the figure. The radius of the wheel is 5 m and the sides of the triangle is 13 m.
Both the wheel and the frame has to be painted.
Find, in mềto 3 significant figures, the area of the region to be painted (the overlapping
region needs to be painted once).
Give your answer without units.

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2

did u ever get the answers? i need
