Answer:
A 29 is the answer to the problem
There are 30-18 = 12 girls. Their percentage is
... 12/30 × 100% = 40%
- 2 because we obtain : - 2x - 2y = - 16 ;
We solve the system:
5x + 2y = 30
-2x - 2y = -16
_____________(+)
3x / = 14;
x = 14/3;
y = 8 - 14/3;
y = 24/3 -14/3;
y = 10/3;
The solution of the system is ( 14/3 ; 10/3 )
