1. (15/5)-(15*5) *this is the numerical expression*
    evaluating the expression: 3-45=-42 (if needed)
2. let x be Annie's age. so, 
   = 2x+10 
3. let x be Romy's age
   = 3x+9 or 3(x+3)
4. 30/2 or simply 15
5. (10+8)² 
if you need an answer for this: 10²+2*8*10+8²
                                      = 100+160+64
                                      = 324.
