If it takes 3 men 5 hours to dig 12 holes, how many hours does it take for 3 men to dig 84 holes?
alexgriva [62]

Answer:

Hence it will take 35hours

Step-by-step explanation:

Let the time it took to dig hole be x

Ley the number of holes be n

Using the relationship x = kn (direct relationship)

if it takes 3 men 5 hours to dig 12 holes, hence;

when x = 5, n = 12

k = x/n

k = 5/12

To get how many hours it take for 3 men to dig 84 holes, then;

when n = 84, x = ?

x = 5/12 * 84

x = 5 * 7

x = 35hours

Hence it will take 35hours

Solve the following system using either linear combination or substitution. Round any answers to the hundredths place. Show all
12345 [234]
So if y=-5x-23 then we can plug that value in for y in x-10y=6, so it becomes

x-10(-5x-23)=6

x+50x+230=6

51x=-224

x=-4.39

plug this x value into the equation y=-5x-23

y=-5(-4.39)-23

y=21.95-23

y=-1.05
