Answer:
A stadium has 49000 seats.
Seats sell for $25 in Section A, z
$20 in Section B,-------------------x seats
$15 in Section C. ------------------y seats
(x+y)=z
25(x+y)+20x+15y=1052000
25x+25y+20x+15y=1052000
45x+40y=1052000
/5
9x+8y=210400------------------1
2x+2y=49000
/2

Answer:
7/24
Step-by-step explanation:
The cost of the jersey with a price of 89 Brazilian real in U.S. dollars is $25.230.
<h3>What is an equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Independent variables represent function inputs that do not depend on other values, while dependent variables represent function outputs that depends on other values.
1 dollar = 5.43 Brazilians real
137 Brazilian real = 137/5.43
= $25.230
Hence, The cost of the jersey is $25.230

M + f + a = 82
m = 7a + 1
f = 1/2m.....f = 1/2(7a + 1).....f = 3.5a + 0.5
7a + 1 + 3.5a + 0.5 + a = 82
11.5a + 1.5 = 82
11.5a = 82 - 1.5
11.5a = 80.5
a = 80.5 / 11.5
a = 7......7 adults
m = 7a + 1
m = 7(7) + 1
m = 49 + 1
m = 50 <=== 50 male students
f = 1/2m
f = 1/2(50)
f = 25 <=== 25 female students
