You have 40 minutes to exercise at the gym, and you want to burn 300 calories total using both machines. if one machiene burns 8 calories a minute and the other burns 6 calories a minute, how much time should you spend on each machine? keep in mind that you have to spend an even amount of minutes at each mechiene.

m represents the number of minutes :) ( idk if its right )

Step-by-step explanation:

8m + 6(40-m)=300

8m + 240 - 6= 300

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)
