Elizabeth works a part time schedule to pay for college. she has worked for the last 14 days without a day off for a total of 48 hours. depending on her schedule she either worked 3 or 4 hours a day. during the 14 day period how many days did elizabeth work for 4 hours a day?

3-hour days = x 

4-hour days = y

(x+y=14)

giving us two equations:

 x+y=14

(3x+4y=48)

 42-3y+4y=48
  

4y-3y=48-42

y=6

x+(6)=14

x=8

Elizabeth worked 6 4-hour days

false

step-by-step explanation:

the reason i say this is because for a certain length of sides you can pick any two and the length is wither equal or greater than the third side and in this case it's not.

3 + 5 = 8

8 is smaller than 9 which is the third side.

hope this : )
