Answer:
21
Step-by-step explanation:
The contiguous U.S. consist of all states beside Alaska and Hawaii; therefore, there are 48 contiguous U.S. states. However, the ratio given to us only consists of 16 states [7 + 9 = 16]. If we need to expand the ratio, we multiply 16 by 3 to get 48. Thus, we also multiply each of the terms by 3, and the ratio becomes 21:27. Therefore, the number of contiguous U.S. states that border an ocean is 21.
Answer:
<em>727 adults</em>
Step-by-step explanation:
In a survey of 1914 adults, 38% responded "yes" to the survey question.
=> The number of adults who answered "yes":
N = 1914 x 38/100 = 727.32 = ~ 727
-9(y + 12) = 4(-7y -8)
Use the distributive property:
-9y - 108 = -28y -32
Add 32 to both sides:
-9y - 76 = -28y
Add 9y to both sides:
-76 = -19y
Divide both sides by-19
Y = 4
