4.  

Since the triangles are similar, set up as ratios

130/60 = (42x+1) /78     now solver for x    multiply both sides by 78

130/60 * 78 = 42x +1

169 = 42x+1

168=42x

x=4

 

5.

Similarly  

18/30 =  (x+19)/55

18/30  * 55 = x+19

33= x+19

x=14

 

6.   Now.....do you think you can do this one?

3x+12/70=24/40

24/40*70=3x+12

42=3x+12

x=10
