Answer:
C. Stacy
Step-by-step explanation:
One way to compare is to convert all the fractions into decimals
Rachel works 2/3 of her shift: Approximately= 0.667
Jose works 1/6: approx. = 0.1667
Damon works 4/5= 0.80
Stacy works 6/7: approx. = 0.8571
Now this makes it much easier to compare
And since 0.85714 (Stacy's shift) is the largest number, Stacy has completed the largest portion of her shift
Answer should be 525.
Work:
Divide the 350 by the 2 parts from 2/3 you should get 175.
The number 175 represents 1/3 so all you have to do now is add 350 by 175.
Y always has to be on the left side so that's what we have to do.
x-4y=12
divide everything by 4 so 4y become y:
1/4x-y=3
-1/4x from each side:
-y=-1/4x+3
switch signs on everything:
y=1/4x-3
Hope this helps :)
