Answer:
The ratio of female-to-male is 1:2
Step-by-step explanation:
There are 10 female students and 20 male students. If we were to divide each number by 10, we would get 1 and 2, respectively. That means for every 1 female student, there are 2 male students. The ratio would then be 1:2.
5x+12=42
x=6
8+x+x+2+3x+2=42
5x=42-12
5x=30
x + 3200 greater than or equal to 10000
you need 6800 more
.
10 i guess
cause
8*3=24
3*10=30
