If the ratio is 4:5 and there is a total of 27 how many does the 4 represent

a² + b²= c²

24² + 7² = c²

c= 25

{3 + i, 3 - i, 3, -1}

step-by-step explanation:

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
