Bailey weighs 5 pounds more than mrs. mcinnes' dog biscuit. bailey is 7 years old. biscuit is 3 years old. together they weigh 75 pounds . how much does bailey weigh?

Bailey weighs 40 pounds. if 75 together and she weighs 5 pounds more than the dog the dog would weigh 35 
40+35=75

This is what i found “an explicit formula designates the nth term of the sequence, as an expression of n (where n = the term's location). it defines the sequence as a formula in terms of n. this example is an arithmetic sequence(the same number, 5, is added to each term to get to the next term).” i hope this you for what your looking for. can you plz mark me brainliest?
