Answer 3

Let's solve these equations step by step:

1. $75 \times 39 + \frac{68}{2} \times 86$ First, calculate the multiplication and division operations: $75 \times 39 = 2925$ $\frac{68}{2} = 34$ $34 \times 86 = 2924$

   Now, add the two results: $2925 + 2924 = 5849$

   So, $75 \times 39 + \frac{68}{2} \times 86 = 5849$.

2. $95 \times 7 + 1290 \times 2$ Calculate the multiplication operations: $95 \times 7 = 665$ $1290 \times 2 = 2580$

   Now, add the two results: $665 + 2580 = 3245$

   Therefore, $95 \times 7 + 1290 \times 2 = 3245$.
