The perimeter of a parrallelogram is 72. the width of the parrallelogram is 4 meters less then it's length. find the width and the length.

to do this you have to do 72/4 = 18 next add 18 + 18= 36 next subtract 36 by 8 which gives you 28 then divide by 2 which gives you 14

the width is 18

for the length do 36 + 8 since your adding  the part you took away from the width to the length which gives you 44 next divide 44 by 2 which gives you 22

the length is 22

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
