If d = the number of dogs, which variable expression represents the phrase below? the sum of the number of dogs and the 6 cats

Hey there!

Based on your question, your answer should be "y = d + 6", where y is the total amount of animals, d is the amount of dogs, and 6 is the number of cats. If you've been given the total amount of animals, you'll replace y with that number. 6 should remain constant since your problem states that there's 6 cats. 

Your answer will be y = d + 6. 

Hope this helped you out! :-)
