Answer:
c = 92/n
Step-by-step explanation:
The equation that describes the inversly proportional relationship is ...
y = k/x
The value of the constant of proportionality can be found from ...
xy = k . . . . . . product of values of independent and dependent variables
__
In this problem, we have c = 23 for n = 4, so the constant of proportionality is ...
k = c×n = (23)(4) = 92
The equation for the relationship is ...
c = 92/n
Answer:
12/7 hours
Step-by-step explanation:
First find the rate for hour for the two. For Lianne she can do 1/3 of the job per hour. For Julie she can do 1/4 of the job per hour.
Adding them together, 1/3+1/4= 7/12.
This 7/12 means that working together they can finish 7/12 of a job in an hour. We can use the speed*time=distance formula here and see that
7/12 * time = 1 job done
time = 12/7 hours.
