Alrighty, so:
Question 9.) We know that each box has a total of three toys, therefore whatever answer we choose must be a multiple of 3. Answer E.) 12 is the only multiple of 3.
Question 10.) The numbers are going up by 13. 63 is what I got as the answer.
Question 11.) A
Question 12.) A
Hope this helps! Been a while since I've done math like this.
