Answer:
28.56
Step-by-step explanation:
Find the perimeter of the square:
4s
= 4×4
=16
Find the circumference of the circle and since it's half circle for both side it's going to be 1 circle:
3.14×d
= 3.14×4
=12.56
Add perimeter of square and circumference:
16+12.56
=28.56
Let the number of men and the number of women in the beginning be x and y
Now,
Now, In 2nd case,
No. Of men=x-63 and no. Of women =y-12
Now,the ratio becomes
Now,we have, 2x=5y
Putting the value of Y=56 in 2x=5y,we get,

Hence, the number of men was 140 and the no. of women was 56

Answer:
1) y = -3
2) y = 0
Step-by-step explanation:
1) When x = 2
4x – 3y = 17
4(2) - 3y = 17
8 - 3y = 17
-3y = 17 - 8
-3y = 9
y = -3
2) When x = 4
–2x + y = –8
-2(4) + y = -8
-8 + y = -8
y = -8 + 8
y = 0
