We can use an approximation of pi. pi = 3.14.
sqrt(16)/4 = 4/4 = 1
2pi = 2 * 3.14 = 6.28
We need to find the number that is not between 1 and 6.28.
A pi = 3.14; 3.14 is between 1 and 6.28, so this is not the answer.
B sqrt(9) = 3; 3 is between 1 and 6.28, so this is not the answer.
C pi/9 = 3.14/9 = 0.349; 0.349 is not between 1 and 6.28, so this is the answer.
D pi^2/9 = (3.14 * 3.14)/9 = 9.86/9 = 1.095; 1.095 is between 1 and 6.28, so this is not the answer.
Answer: C pi/9
<em>An adult ticket costs $205 and a child ticket costs $49.</em>

Hello! Recall you have to write complete questions in order to find exact answers. Here I'll assume the complete question as:
<em>Two families are planning a trip to Disney. The Smith family bought tickets for 2 adults and 3 children for $557. The Jones family bought tickets for 2 adults and 1 child </em><em>for $459</em><em>. How much does and adult and child ticket cost?</em>
To solve this problem, we need to write a system of linear equations in two variables. So, we know some facts:
- Two families are planning a trip to Disney.
- The Smith family bought tickets for 2 adults and 3 children for $557.
- The Jones family bought tickets for 2 adults and 1 child for $459.
Let:
For the Smith family:
Cost for the 2 adults:
Cost for the 3 children:
Total cost:
For the Jones family:
Cost for the 2 adults:
Cost for the 1 child:
Total cost:
So we have the following system of linear equations:
Subtracting (2) from (1):
Finally, <em>an adult ticket costs $205 and a child ticket costs $49.</em>

Answer:
2 yards 5 inches will be equivalent to 77 inches
Step-by-step explanation:
Given length -
2 yards 5 inches
One yard has 36 inches
Two yards will have 2*36 = 72 inches
Thus, 2 yards 5 inches will sum up to 72 inches + 5 inches = 77 inches
Hence, 2 yards 5 inches will be equivalent to 77 inches
Answer:
5x-5 = 5(x−1)
X-23 = =x−23
