is the correct answer of this question
Answer:
substituting x=5y into 2x-3y=7, Answer: y = 1 x = 5
Step-by-step explanation:
2(5y)-3y=7
10y-3y=7
7y=7
y=1
substitute y=1 into x=5y
x=5(1)
x=5
2 * x/100 = 8
x/100 = 4
x = 400
400%
In equation, let x be the number of male students
a be the number of adults
y be the number of female students.
x= 7a+1
a= x/7 -1
y= x/2 or (7a + 1)/ 2
a + b = 82, let b be the number of students.
a + (x + y) = 82
a + [7a+1 + (7a+1)/2] = 82
a + [{2(7a+1) + 7a+1} / 2] = 82
a + [(14a +2 + 7a +1) / 2] = 82
a + [(21a + 3) / 2] = 82
(2a+ 21a + 3) / 2 = 82
(23a + 3) / 2 = 82
23a + 3 = 164
23a = 164 -3
23a = 161
a = 7
x = 7(7) +1, 49+1 = 50 male students
y=x/2, 50/2, 25 female students
50(male students) + 25(female students) + 7 (adults) = 82
