9) The product of 4 and an unknown number is -52. What is the unknown number?

The uknown number is -13

Step-by-step explanation:

let n be the unknown number.

Since the question says "the product of 4 and an uknown number" it should be 4n = -52 (the question says 4n should be equal to -52).

Now, divide by 4 on both sides

n=-13.

Hope this help!
