Answer:
1/10
Step-by-step explanation:
Julie read 5/10 in the morning and had 4/10 left to read after what she read at night. At night, she read ...
1 - 1/2 -2/5 = 10/10 -5/10 -4/10 = 1/10
Julie read 1/10 of the book at night.
Answer: she read 1/10 of the book at night.
Let x represent how much of the book that Julie read at night.
Julie read 1/2 of a book in the morning, and she read some more at night. This means that she has read
1/2 + x = (1 + 2x)/2 of the book by night. The portion of the book remaining would be
1 - (1 + 2x)/2 = [2 - (1 + 2x)]/2
= (1 - 2x)/2
By the end of the day, she still had 2/5 of the book left to read. Therefore,
(1 - 2x)/2 = 2/5
Cross multiplying,
5(1 - 2x) = 2 × 2
5 - 10x = 4
10x = 5 - 4 = 1
x = 1/10

Answer: 9 boxes
A. 2 (0)=0
B. 2 (2)=4
You have to multiply the X numbers by 2 for example 2x , x=2 , 2x2=4
