If m angle abf=7b-24 and m angle abe=2b find m angle ebf

angle ABE is equivalent to the whole angle, and it measures 2b. 
while the angle ABF is only a portion of angle ABE, and it measure 7b - 24. 

since we know the measure of the whole angle and a part of the angle, we can then subtract to find the left over angle (angle EBF), so

Angle EBF = Angle ABE - Angle ABF 

Angle EBF = 2b – (7b – 24)

Angle EBF = 24 – 5b

7 weeks

step-by-step explanation:

convert each fraction to the least common multiple of 20, so 3/4 = 15/20 & 1/10 = 2/20, then divide 15 by 2 and you get a little over 7, so the food will last 7 weeks.

36/60

36/2=18

60/2=30

18/30

18/3=6

30/3=10

6/10

6/2=3

10/2=5

your final answer would be 3/5 of an

hope this !
