G = number of girls;
b= number of boys
we know that: g= 6+2b
      and that: g+b= 156 kids in total 
so we may write  g+b=(6+2b)+b=6+3b
                  but g+b= 156 
so 6+3b = 156 => 3b= 156-6=150 =>   b=150/3=50 => b = 50 (number of boys)
g= 6+2b= 6+2 x 50= 106 => g =106 (number of girls)

ira [324]

Answer:

x = \frac{25}{7}

A segment joining the midpoints of 2 sides of a triangle ia

Parallel to the third side and half the length of the third side, thus

7x - 1 = 24 ( add 1 to both sides )

7x = 25 ( divide both sides by 7 )
