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

A)

5 (x - 8) - 7 = 40

B)

5 (8 - x) - 7 = 40

C)

7 (x - 8) - 5 = 40

D)

7 (8 - x) - 5 = 40

D.) 7 (8 - X) - 5 = 40

let X = unknown number

eigth minus a number is 8 - x. since the product is seven and eight minus a number then 7 * [8-x] or 7 (8-5).

40 is its equivalent when the product is decreased by 5; therefore, 7 (8-x) - 5 = 40.
