Verified answer

Answer:

8

Step-by-step explanation:

These kinds of problems don't deal with simple arithmetic but instead patterns. The pattern follows the number of letters

five (4) + six (3) = 7

seven (5) + eight (5) = 10

three (5) + nine (4) = 9

seven (5) + ten (3) = 8

Therefore, 7 + 10 for this problem is 8.
