It would be 7:9 because if you divide each side by 4 then you can get it in simplest form
Answer:
C) 40
Step-by-step explanation:
For every one day your work is 5 hours.
1 day = 5 hours
Set up a proportion so it would be:

4 days x 5 hours = 20 hours/week
So now you know you know you work 20 hours/week, then multiply by 2 since they're asking how many hours will you work in two weeks:
20 hours x 2 weeks = 40 hours in two weeks
Im learning this too right now hope this helps
1.you get y by itself and put what y equals where y is in the other equation
y=2x. x+y=12
x+2x=12
3x=12. (divided 3 on both sides)
x=4
2.after you find x(or y) put it in one of the problems above and solve for whats missing which in this case is y
y=2(4) 4+y=12
y=8. -4. -4
y=8
