Verified Answer :

the answer is 500, you can divide 3500 by 7 and get 500.then double check by multiplying 500 by 7

Call the number 'x'.
Then set up an equation to represent the relationship:
\(7x=3500\)
Then solve for 'x':
First dicide both sides by 7:
\(\frac{7x}{7}=\frac{3500}{7}\)
And simplify:
\(x=500\)
Then answer the question: "The number is 500."
