Once your friend has thought of a number, do the following:
1. Ask him or her to multiply the chosen number by 2.
2.Choose an even number to use yourself. Ask your friend to add this number to the one in his head.
3.Tell him/her to divide the new number by 2.
4.Tell your friend to subtract his original number from the equation.
5."Guess" the number.

-7, because you distribute it to both -4 and 3.2, which means you're multiplying it to both.
Let the partitions of the segment be 5k and 3k .
.
5k+3k = length of segment
Suppose the length of segment is y
8k = y
k = y/8
.
Hence ,
5k = 5(y/8)
3k = 3(y/8)
.
As the value of the segment wasn't given , it seems a bit complicated..

Hope u understand!
Answer:
The total amount of recyclables sorted by Amirah is 931 pounds.
Step-by-step explanation:
Amount of cans and bottles sorted = 263 pounds
Amount of paper sorted = 668 pounds
So, the total amount of recyclables sorted
= amount of cans and bottle sorted + amount of paper sorted
= 263 pounds + 668 pounds
= 931 pounds
Hence, the total amount of recyclables sorted is 931 pounds.
