so two fellows did all the carpeting in 10 days.

now, how long did "1" fellow work only?  well, it worked for 10 days.

how long did the other fellow work for?  well, it was working alongside the first one, and it was there for also 10 days.

so the two guys working together, really did 10+10 = 20 "days worth of work".  So that the whole carpeting job can be done in 20 "days worth of work".

now if we want to finish it in 4 days, 20 ÷ 4 = 5.

so if we hire 5 guys, since each one will do 4 days worth, 5*4 = 20 <- the whole job.

Answer:

5 worker

Step-by-step explanation:

Two men complete carpeting = 10 days

Total time taken to complete the work= Number of men× Number of days

Total time taken to complete the work= 2×10

Total time taken to complete the work= 20

Let x number of men complete the work in 4 days

According to question

4×x= 20

x= 20÷4

x=5 men

Number of 5 worker are required to complete the work in 4 days

Answer:

y= -x+7, b= sqrt(2P/a), c=3P^2-b

Step-by-step explanation:

First, make a table regarding both of the equations. You will eventually find out that both lines intersect at the point (2, 5) after you find the points on the table. From there, subtract x from both sides in the equation x + y = 2. You will      get y = -x + 2. Since they said the line was parallel, find a line that has the slope of negative one. Since we know that this line intersects the point in which the first two lines intersect, we know that the y-intercept will be 7. The equation of the line would be y=-x+7.

Multiply both sides by 2. Then, divide both sides by a to get b^2=(2P/a). Take the square root to get the value of b, which is sqrt(2P/a).

Square both sides of the equation to get P^2=(b+c)/3. Cross multiply to get 3P^2=b+c. Subtract b from both sides to get c=3P^2-b.

Hello!

The slope intercept form is y=mx+b, where m is the slope and b is the y-intercept.

First, let's find the y-intercept. This is where the line hits the y-axis. Therefore, it hits at 4 on the y-axis, so our y-intercept is 4.

To find the slope, let's find 2 points on our line. Let's use (0,4) and (2,5). We divide the difference in the y-values by the difference in the x-values as shown below.

\frac{5-1}{2-0} =\frac{4}{2} =2

Therefore, our slope is 2.

Now we plug these values into our equation.

y=2x+4

I hope this helps!
