Find the midpoint of the segment with the given endpoints (5,-9) and (-2,-2)
QveST [7]
Another way to solve this is to use the Midpoint Formula.  The midpoint of a segment joining points (x_1,y_1) and (x_2,y_2) is

\left(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2} \right)

So the midpoint of your segment is

\left(\frac{5+(-2)}{2},\frac{-9+(-2)}{2}\right) = \left(\frac{3}{2},-\frac{11}{2} \right)

Perhaps it helps to see that the x-coordinate of the midpoint is just the average of the x-coordinates of the points.  Ditto for the y-coordinate of the midpoint; just average the y's.

The equation that corresponds to this diagram is 6 (x+ 1)=24.
Annette [7]

Answer:

x is 3

Step-by-step explanation:

6 (x + 1) = 24

6 (x) + 6(1) = 24

6x + 6 = 24

Subtract 6 on both sides

6x + 6 - 6 = 24 - 6

6x + 0 = 18

6x = 18

x = 18/6

x = 3

It takes 9 builders 54 days to complete a house.
Dima020 [189]

It would take 6 builders  36 days to complete the same house.

<h3>Who are builders?</h3>

Builders are those person whose job is to build or repair houses and other buildings.

We have,

9 builders take 54 days to complete a house.

So,

1  builder will take  (\frac{54}{9})  days to complete a house,

In the same way,

6  builder will take  (\frac{54}{9}*6)  days to complete a house,

i.e.

6  builder   =(\frac{54}{9}*6)= 36 days.

Hence, we can say that it would take 6 builders  36 days to complete the same house.

lee = 2(x÷7)

(x÷7)+2(x÷7)

Step-by-step explanation:
