Answer:
+12.5%
Step-by-step explanation:
This is rather simple. Subtract 72 from 81, then put the difference over 72. Then, multiply that by 100.
(81 - 72)/72 * 100
<em>Subtract 72 from 81 to get 9</em>
9/72 * 100
<em>Multiply 9 by 100 to get 900</em>
900/72
<em>Simplify the above fraction by cancelling out 9.</em>
100/8
<em>Divide 100 by 8 to get 12.5%</em>
The percent of change is +12.5%
Answer:5π/12
Step-by-step explanation:
180°=π
75°=x
x=75π ➗ 180
x=5π/12
Step-by-step explanation:
First, subtract 24 - 14 to get how many books he had after he sold half of his collection and bought 14 more:
24 - 14 = 10
10 = number of books after he sold half of his collection.
Now, you need to multiply 10 x 2, because you need to find the original number of comic books:
10 x 2 = 20
He originally had 20 comic books.
An equation you could use for this question is:
2(24 - 14) = x. (X = number of comic books)
