A company uses this formula to work out the cost, £A, of a taxi ride. A = 5 + 1.9m + b
£5 is a fixed charge
m is the number of miles travelled
£b is a charge for booking online
a) Harry books a taxi online and travels 12 miles.
He pays £29.48 altogether.
How much is the charge for booking online?
b) If Sue books online and travels 20 miles, what will be

answer is 144

step-by-step explanation:

12

step-by-step explanation:

12 + 5 = 17

12x2=24

24-7=17

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)
