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
9x=18
so x=2
then 2 times 4 which equals 8
and 2 times 5 which equals 10
so there are 8 girls and 10 boys

Answer:
193.2
Step-by-step explanation:
To solve the triangle:
5.2 × 6= 31.2
You would normally find half of that since it's a triangle but there are two triangles, so each would equal half of 31.2 but if you add both halves that just equals 31.2.
Square one:
9 × 6= 54
All three squares are equal since they have the same measurements.
54 + 54 + 54= 162
162 + 31.2= 193.2

F^-1(x) is the inverse so...
f^-1(x) = (-1/5)x - 11/5
