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.

Cole and his sister chloe are cleaning their house. The house has nine rooms in it. If it take one person about 18 minutes to cl
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}
