Nathan does push ups for the same amount everyday. he does 9 minutes of push ups for 3 days. how many minutes of push ups does nathan do in 7 days?

21 minutes

work: okay, so to solve this we need to find the unit rate, or number of minutes he spends doing pushups each day, to be ale to see how many he does in 7 days.

so, to find the unit rate, divide the number of minutes by days.

9/3 = 3

so, this means he spends 3 minutes a day on pushups.

to find out how many he completes in 7 days, multiply how many minutes he spends a day (3) by the number of days (7)

3 x 7 = 21

so, he spends 21 minutes doing pushups in 7 days.

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)
