Hello,
Let denote
h the number of men in the concert hall (before leaving)
f the number of women in the concert hall (before leaving)
1/5 h quit =60/2
15/100 f =60/2
h=30*5=150
f=30*100/15=200
Tey were 150+200 = 350 humans in the hall.
(why h : homme, f:femme you may call m and w)
Which sentence?
when you give the sentence,I will answer☼
The first step to solving this is to solve the equation for x
x = - 21/5 - y
4x + 4y = -14
now,, substitute the given value of x into the equation "4x + 4y = -14"
4( - 21/5 - y) + 4y = -14
next,, solve the equation for y
y∈∅
since this system has no solution for y, your answer is (x,y)∈∅
let me know if you have any further questions

The area's of a triangle is bh/2 and a parallelogram's area is bh. so if they have the same base and the same height then they are related by the paralleogram being 2 the triangle.
