Pretty sure the answer is 29/20 or 1 9/20. You get this by find the common denominator , 60, and then adding the number all together and simplifying
Exterior angles for n sides = 360/n = 17.14, n = 360/17.14 = <span>21 sides</span>
Using the probability concept, it is found that there is a 
probability the student is a boy.
<h3>What is a probability?</h3>
- A <em>probability </em>is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
In this problem, according to the two-way table found on the internet when we research the problem:
- There are 11 people who are 12, of which 4 are girls and 7 are boys.
- Hence, in total, there are 21 people, of which 13 are girls and 8 are boys.
- Then, we find that there are 10 people aged 11, of which 6 are girls and 4 are boys.
Then:
There is a probability the student is a boy.

Answer: 0
Step-by-step explanation:
Let statements :
Let x be the number of tickets sold for an adult
Let y be the number of tickets sold for a child
Equations :
x + y = 280 OR y = 280 - x
4x + 2y = 1320
Substitution (sub the 2 equations in together) :
4x + 2(280 - x) = 1320
4x + 560 - 2x = 1320
2x = 1320 - 560
x = 760/2
x = 380
x is the number of tickets sold for the adults. meaning that 380 adults went.
Find the # of children :
x + y = 380
we know that x = 380
380 + y = 380
y = 380 - 380
y = 0
Conclusion :
No children went because the movie was rated R. Only adults attended.
Answer:
2
Step-by-step explanation:
57x + 1 = 115
