Answer:
Step-by-step explanation:
This is an inverse proportion.
men = k / Time So first we need to find k
k = men * Time Substitute values
k = 15*80
k = 1200 Notice the units are man days.
Now what happens if we increase the number of men to 20? What happens to the number of days.
20 = 1200 / time Multiply both sides by time
20*time = 1200 Now divide by 20
time = 1200/20
Answer: time = 60 days

Answer:
4 apples adding 4 and adding 4 again = the amount you have
Step-by-step explanation:
draw 3 groups of 4 apples
Answer: 17
Step-by-step explanation:
We can tell that for every 2 changes in X there is 8 points lost in y
meaning that if we do 8 /2 we get 4
Every 1 change in x there is 4 points of change in Y
so if (3,5) Then (0,17)
17 - 5 = 12 And 3-0 = 3 So for 3 points of change for Xthere were 12 points of change for Y so this is right
