There are two thousand girls and one thousand boys at a university. for every girl with glasses there are two boys who were glasses .20 percentage of all students were glasses. how many boys were glasses?

200

Step-by-step explanation:

2000 girls :1000 boys

2000 +1000 =3000

20% of 3000 = 600

I girl : 2 boys

1+2=3

600÷3 = 200

200 boys wore glasses

ome people is not even worth it to even try it in the air.

step-by-step explanation:

answer: integers are just whole numbers: positive, negative, and zero.

i = {-∞, -2, -1, 0, 1, 2, 3, ∞}

let x = 1st integer

let y = 2nd integer

x = 3y + 17   {equation 1}

xy = -24         {equation 2}

substitute 3y+17 in place of x n equation 2

and solve for y.

(3y+17)y = -24

3y2 + 17y = -24

3y2 + 17y + 24 = 0

from quadratic equation:

y = [-17±√(172-4(3)(24))]/(2(3))

y = (-17 ±√1)/6

y = (-17+1)/6   or     y = (-17-1)/6

y = -16/6           or     y = -18/6

y = -2 2/3         or   y = -3

since we are dealing with

y = -3

x = 3y+17 = -9+17 = 8

the integers are -3, 8
