13 1/8 and as a decimal it’s 13.125
Given :
Tickets cost $3 for students and $5 for adults.
A total of 125 people attended the concert for a total ticket sales of $475.
To Find :
The number of students and adults that attended the concert.
Solution :
Let, number of students and adults that attended the concert is x and y.
Mathematical equation of given conditions :
x + y = 125 ....1)
3x + 5y = 425 ....2)
Putting value of x from 1 to equation 2 is :
3( 125 - y ) + 5y = 425
375 - 3y + 5y = 425
2y = 50
y = 25
x = 125 - 25
x = 100
Therefore, number of students and adults that attended the concert is 100 ans 25 respectively.
Hence, this is the required solution.

Answer:
3 3/16
Step-by-step explanation:
You want s such that ...
(2 1/2)/(3 1/3) = s/(4 1/4)
Multiplying by 4 1/4 gives ...
s = (4 1/4)(2 1/2)/(3 1/3)
A calculator can help you find the value of this expression. As a decimal, it is ...
3.1875
If you're familiar with decimal equivalents of fractions, you know this can be written as the mixed number ...
3 3/16
_____
If you do the above math the "pencil and paper" way, you get ...
s = (17/4)(5/2)/(10/3) = (17·5·3)/(4·2·10) = 51/16 = 3 3/16
Answer:
b =15
Step-by-step explanation:
The sum of the angles of a triangle is 180
5b+ 4b+ 3b = 180
12b = 180
Divide by 12
12b/12 =180/12
b =15
