Since 15 workers did 8 hours of work, the total amount of work needed is 120 hours. Half of this job would be 60 hours. Then divide this amount by the 5 workers doing the job. This would make the job 12 hours

J=15w*8h=120(worker*hours)

5h=120/2

5h=60

h=12 hours

State whether the relationship between x and y in y = 0.5x is proportional or non-proportional. Then graph the function.
Mars2501 [29]

Step-by-step explanation:

A relationahip is proportional if both variables can be both 0.

y = 0.5x

(0) = 0.5(0)

Since the equality is true, it is proportional.

To graph the function, plot (0, 0) and (10, 5) on the graph and draw a line through the points.
