12 roofers did a job in 65 1/3 hrs, how long woukd it take 29 roofers?

It will take [/tex]27\frac{1}{29} \text{hr}[/tex] or 27.034 hr to complete the job.

Step-by-step explanation:

Consider the provided information,

12 roofers did a job in 65 1/3 hrs,

That means 1 roofer can do the same job in:

1 roofers will complete the work in

Now we need to find time taken by 29 roofers.

29 roofers will complete the work in

Hence, it will take or 27.034 hr to complete the job.

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)
