Find the coordinates of the midpoint of the segment whose endpoints are given.

Afina-wow [57]

You can think of midpoint as being an average.
Add the values and divide by 2.
(x1 + x2)/2, (y1 + y2)/2

(2 + 6)/2, (3 + 11)/2
(4,7) would be the midpoint

alex41 [277]

Answer: Cole and his sister Chloe will take 81 minutes to clean the whole house.

Step-by-step explanation:

Total rooms in the house = 9

Total persons to clean the house = 2 (Cole and his sister Chloe)

Time taken by 1 person to clean one=18 minutes

Time taken by 2 persons to clean one room together=18 divided by 2 = 9 minutes

Time taken by 2 persons to clean 9 rooms (which is the total number of rooms in the house)=9 multiply 9 = 81 minutes

therefore, they will take 81 minutes to clean the whole house.

Solve for x. Express the answer in simplest form.

natta225 [31]

1. Multiply both sides by 4x-1
   $\frac{1}{7} (4x-1)=3$
2.Simplify $\frac{1}{7} (4x-1) to \frac{4x1}{7} 
$
   $\frac{4x-1}{7} =3$
3.Multiply both sides by 7
   4x-1=3x7
4.Simplify 3*7 to 21
   4x-1=21
5. Add one to both sides
   4x=21+1
6. Simplify 21+1 to 22
   4x=22
7.Divide both sides by 4
    x= $\frac{22}{4}$
8.Simplify $\frac{22}{4}$ to $\frac{11}{2}$
