Answer:

Step-by-step explanation:

The product of eight minus a number and seven equals forty when decreased by five. Which equation represents the sentence?

weeeeeb [17]

The "product" of two numbers means you multiply them.

So, you are multiplying (8-n), where n = "a number," by 7.

Then, when you decrease (subtract) this product by 5, you get 40.

So the whole thing looks like

7(8-n) - 5 = 40.
