After ricardo received his allowance for the week he went to the mall with some friends he spent half of his allowance on anew paperback book the he brought himself a snack $1.25 when he arrived home he had $5.00 left how muchwas his allowance

$12.50

Step-by-step explanation:

Let Ricardo received the allowance = x dollars.

He spent half of her allowance on a new paper back book

so amount left with him = x -

                                      =

then he bought a snack with the amount = $1.25

amount left = ( - 1.25)

When he reached home amount with him = $5.00

Therefore, -1.25 = 5

                = (5 + 1.25)

                = 6.25

                x = 2 × 6.25

                x = $12.50

Ricardo received allowances = $12.50

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)
