Can anyone help with this?

AD = 15

Step-by-step explanation:

Based on the Pythagoras Theorem, the longest side of a right-angled triangle is: where a and b are the legs of the triangle.

In triangle BDC, we can put in the formula to find BD.

85 =

85² = 77² + BD²

7225 = 5929 + BD²

BD² = 7225 - 5929

       = 1296

BD =

BD = 36

In triangle ABD, we can put in the formula to find AD.

39 =

39² = 36² + AD²

1521 = 1296 + AD²

AD² = 1521 - 1296

       = 225

AD =

AD = 15

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

i think u have 12 apples sorry again i don't really know if it correct i'm just tryna hrlp people out.
