Answer:
2 /10
Step-by-step explanation:
The portion of the book that weight 2 1/8
Total number of books = 10
Number of books that weight 2 1/8 = 2
Fraction of book that weigh 2 1/8 = number of books that weigh 2 1/8 / total number of books
Fraction = 2 / 10
1/8 + 3/4 = 1/8 + 6/8 = 7/8 (to the right)
1/8 - 3/4 = 1/8 - 6/8 = -5/8 (to the left)
Answers are 7/8 and -5/8.
Answer:
x=23
Step-by-step explanation:
The two angles are equal so you can set 8x-77 and 3x+38 equal to each other and write it as:
8x-77=3x+38
Then you get like terms on the same sides by subtracting 3x from both sides and getting:
5x-77=38
Then you add 77 to both sides and get:
5x=115
Then you divide both sides by 5 and get x=23
