Answer:
-3 is a solution
Step-by-step explanation:
4x+2 < -6
subtract 2 from each side
4x < -8
divide by 2
x < -2
-3 is a solution
The ratio is 4:5
so girls=4x
and boys=5x
(because you don't know how many boys or girls there are)
then the equation would be
4x+5x=18

then 2 times 4 which equals 8
and 2 times 5 which equals 10
so there are 8 girls and 10 boys
