Answer :

Let's solve this step-by-step:

1. Convert the 3-kilogram packages to grams:
- 1 kilogram (kg) is equal to 1000 grams (g).
- Therefore, 3 kg is equal to [tex]\( 3 \times 1000 = 3000 \)[/tex] grams.

2. Calculate the weight for two 3-kilogram packages:
- If one 3-kilogram package is 3000 grams, then two packages would weigh [tex]\( 2 \times 3000 \)[/tex] grams:
[tex]\[ 2 \times 3000 = 6000 \text{ grams} \][/tex]

3. Calculate the total weight of five 535-gram packages:
- One package weighs 535 grams.
- Therefore, five packages weigh [tex]\( 5 \times 535 \)[/tex] grams:
[tex]\[ 5 \times 535 = 2675 \text{ grams} \][/tex]

4. Add the weights of the two sets of packages:
- The total weight is the sum of the weight of the two 3-kilogram packages and the five 535-gram packages:
[tex]\[ 6000 \text{ grams} + 2675 \text{ grams} = 8675 \text{ grams} \][/tex]

Hence, the total weight of the two 3-kilogram packages and five 535-gram packages of toy bricks is:
[tex]\[ 8675 \text{ grams} \][/tex]

So, the correct answer is:
[tex]\[ \boxed{8675} \][/tex]
